The internal keyboard on the Lenovo IdeaPad Slim 3 15IWC11 (83RR)
does not work correctly with the default i8042 settings. Using
i8042.nopnp=1 and i8042.dumbkbd=1 restores keyboard input, but prevents
the Caps Lock LED from working. Using i8042.nopnp=1 alone does not fix
the keyboard.
The laptop works correctly when atkbd_deactivate_fixup is used instead.
Add a DMI quirk for the 83RR to enable it.
This was tested without any i8042 command-line parameters. Keyboard
input and the Caps Lock LED work correctly, including after suspend
and resume and after a cold boot.

System suspend powers the controller off and resume powers it back on,
but the resume path enables the interrupt before s6sy761_power_on()
checks the boot. The firmware raises its boot-complete event on the
interrupt line, the threaded handler consumes it, s6sy761_power_on()
then reads an empty event and resume fails with -ENODEV, skipping the
touch function setup:
s6sy761 2-0048: PM: dpm_run_callback(): s6sy761_resume [s6sy761] returns -19
Power the chip on first and only then unmask the interrupt. Once resume
completes the boot handshake the chip comes back with sensing off, as
at probe where input_open() turns it on, so the touchscreen stays dead
after resume. Send SENSE_ON again when the input device is open.
Tested on a Pixel 3 XL over several s2idle cycles: resume succeeds and
the touch function and sense status match the pre-suspend state.

The ThinkPad L440 also uses board id 2722, but does not have the SMBus
initialization problem seen on the T440p. On the L440, the SMBus
companion becomes available shortly after psmouse probes, allowing the
touchpad to use SMBus/RMI4 normally.
The T440p's quirk is currently applied to all Synaptics touchpads with
board id 2722, unnecessarily disabling SMBus InterTouch on the L440,
as reported by Daniel Salmun.
Restrict the quirk to PNP ID LEN0036, which identifies the T440p, so
that other devices sharing board id 2722 retain their normal

hp_sdc_kicker() rearms hp_sdc.kicker with mod_timer() after scheduling the
tasklet. The module exit path uses timer_delete_sync(). That waits for a
callback already running but can still leave the timer rearmed.
A callback can therefore leave the timer pending while hp_sdc_exit() tears
down the driver, allowing timer activity to access dismantled driver state.
Use timer_shutdown_sync() for final teardown. It waits for a running
callback and prevents rearming after module exit begins.

On the MS Surface Pro 11 soc_button_array probing races with the GPIO
driver probing. If soc_button_array wins the race then gpiod_get() returns
EPROBE_DEFER, which should normally take care of retrying later, but
the soc_button_array code deliberately ignores EPROBE_DEFER causing it
to fail its probe() which causes the volume and power buttons to now work.
The ignoring of EPROBE_DEFER is there to deal with a problem specific to
older Bay Trail (BYT) and Cherry Trail (CHT) tablets which often use this
driver. Modify the error handling to only ignore EPROBE_DEFER on BYT and
CHT platforms and propagate EPROBE_DEFER normally on other platforms.

The Lenovo ThinkPad T440p (PNP ID LEN0036, board id 2722) has a
Synaptics touchpad whose SMBus companion is not ready at boot and
takes roughly 200 seconds to appear. During this window the touchpad
and TrackPoint are completely unresponsive on approximately 50% of
boots, making the machine unusable until the companion finally
registers.
The device is in the topbuttonpad_pnp_ids[] SMBus allowlist, so the
kernel attempts to use SMBus/RMI4 mode by default. When the companion
is not ready, psmouse_smbus_init() leaves breadcrumbs and returns
-EAGAIN, the PS/2 fallback path is taken, but the device does not
function properly until the companion appears and RMI4 takes over.
Disable SMBus InterTouch for board id 2722 so the touchpad and
TrackPoint work immediately via PS/2 from boot. Users can still force
SMBus with psmouse.synaptics_intertouch=1 if needed.

In the compat path input_ff_effect_from_user() aliases the caller's
native struct ff_effect with the smaller struct ff_effect_compat and
copies only the compat sized prefix:
compat_effect = (struct ff_effect_compat *)effect;
if (copy_from_user(compat_effect, buffer,
sizeof(struct ff_effect_compat)))
The tail of the native structure is never written. Callers pass an
uninitialized on-stack object, for example evdev_do_ioctl() for
EVIOCSFF, so those bytes keep their previous stack contents.
input_ff_upload() then stores the full native structure in
ff->effects[id], from where a uinput based force feedback daemon can
read it back via UI_BEGIN_FF_UPLOAD, disclosing kernel stack memory to
userspace.
Zero the effect before the compat copy.

The EVIOCSABS handler copies at most the user supplied ioctl size into
an uninitialized on-stack struct input_absinfo:
if (copy_from_user(&abs, p, min_t(size_t,
size, sizeof(struct input_absinfo))))
The size comes from _IOC_SIZE() of the ioctl command and is therefore
fully controlled by userspace. A short size leaves the trailing part of
the structure holding whatever was on the kernel stack, and the whole
structure is then stored into the device:
dev->absinfo[t] = abs;
EVIOCGABS hands that back to userspace, disclosing the stale stack
bytes. Only the resolution field is currently cleared, which covers the
legacy struct layout but not an arbitrarily short size.
Zero the structure before the copy so any part not supplied by the
caller reads back as zero. The existing resolution fixup is kept, since
it also handles a size that partially overlaps that field.

Transport drivers (such as rmi_i2c and rmi_spi) invoke
rmi_driver_suspend() and rmi_driver_resume() on their child rmi_dev
device during system power management events. However, transport drivers
are fully registered and operational even if the physical RMI driver
failed to bind or probe the rmi_dev device.
When rmi_driver_suspend() or rmi_driver_resume() is called on an unbound
rmi_dev, dev_get_drvdata() returns NULL. Calling rmi_disable_irq() or
rmi_enable_irq() without driver data attached causes a NULL pointer
dereference and General Protection Fault when attempting to lock
data->enabled_mutex.
Fix this by checking if driver data is attached to rmi_dev in
rmi_driver_suspend() and rmi_driver_resume(), exiting early if
no driver data is present.

When chunking writes into SMBus blocks in rmi_smb_write_block(), the
loop calculates block_len using the original total length (len) instead
of the remaining length (cur_len).
If len is greater than 32 bytes (SMB_MAX_COUNT), block_len remains 32
for every iteration, even on the final partial chunk where fewer than 32
bytes remain. This causes smb_block_write() to read 32 bytes from the
advanced data buffer pointer, reading past the end of the input buffer.

and address pointers by block_len.

The internal keyboard of the Xiaomi Redmi Book Pro 16 2026 (board TM2425)
does not work: atkbd_probe() succeeds and every command is ACKed, but no
scancodes ever arrive afterwards.
Testing on the hardware through serio_raw shows that ATKBD_CMD_RESET_DIS
(0xF5) is the culprit. After 0xF5 the embedded controller keeps ACKing
commands but stops delivering scancodes, and neither ATKBD_CMD_ENABLE
(0xF4) nor ATKBD_CMD_RESET_BAT (0xFF) bring them back. Only re-enabling
the keyboard interface at the controller level (i8042 command 0xAE, or
rewriting the command byte as i8042_port_close() does) revives it.
Running the init sequence without 0xF5 (0xED 0x00, 0xF3 0x00, 0xF4)
keeps the keyboard working.
'i8042.dumbkbd=1' also works around this, but then the driver never
writes to the keyboard and the LEDs cannot be controlled. Use the
existing atkbd_deactivate_fixup quirk instead, as done for the sibling
TM2424 by commit 3a046db33b ("Input: atkbd - skip deactivate for

So as not to clobber any pre-programmed GPIO state in the execution
of its gpiochip ops, the driver caches things during probe time.
However, since those ops can be called both during and immediately after
the call to devm_gpiochip_add_data(), it is imperative that things are
cached before that. That's not the case right now, so reorder the two
steps to prevent any clobbering.
In the concrete example which motivated this change, a bootloader was
preconfiguring an important GPIO output to HIGH before booting the
kernel. Linux would then inadvertently set that output to LOW while
configuring a GPIO hog on a discrete GPIO line within the same 8-bit
bank (because the cached value was 0=LOW).

In sur40_probe(), if video_register_device() fails, the error path jumps to
err_unreg_video. This incorrectly attempts to unregister a video device
that was never successfully registered, and fails to free the V4L2 control
handler (v4l2_ctrl_handler_free) that was initialized immediately prior.
Fix this by introducing an err_free_ctrl label to properly free the V4L2
control handler and bypass video_unregister_device() when video device
registration fails.

In sur40_probe(), input_register_device() was previously called early before
the V4L2 video device and vb2_queue components were fully initialized. If
userspace opened the input device immediately upon registration, sur40_open()
would trigger and start the sur40_poll() worker thread. This worker thread
invokes sur40_process_video() and accesses the uninitialized vb2_queue
structure, leading to a data race and potential system crash.
Furthermore, if V4L2 or video registration failed after input_register_device()
succeeded, the error path fell through to calling input_free_device() on a
successfully registered device instead of input_unregister_device(), corrupting
input core state.
Move input_register_device() to the very end of sur40_probe(). This ensures
the V4L2 and video queue structures are fully initialized before polling can
start, and naturally resolves the error path bug since input_free_device()
is now only called when input registration has not yet occurred.
To maintain strict LIFO (Last-In, First-Out) teardown ordering, also move
input_unregister_device() to the very beginning of sur40_disconnect(). This
guarantees that the input polling worker thread is stopped before V4L2
video components or control handlers are unregistered.

The user-supplied event type index passed to EVIOCGMASK / EVIOCSMASK
ioctls is used to index the static counts array in evdev_get_mask_cnt()
and client evmasks array in evdev_get_mask().
While the event type is architecturally bounded by EV_CNT, speculative
execution may mispredict bounds checks and perform out-of-bounds loads.
Sanitize the event type index in evdev_get_mask_cnt() branchlessly using
array_index_mask_nospec(). This clamps the index to 0 for safe array
access and forces the returned count to 0 speculatively when the index
is out of bounds.
We do not need additional array_index_nospec() calls in evdev_get_mask()
because evdev_get_mask_cnt() speculatively forces the count (and
resulting xfer_size) to 0 for out-of-bounds types, preventing any
speculative memory access to client evmasks array.

When an input device is being unregistered via input_unregister_device(),
input_disconnect_device() sets dev->going_away = true under dev->mutex
and releases the mutex.
If a concurrent sysfs write to the inhibited attribute executes
input_inhibit_device() or input_uninhibit_device(), it acquires
dev->mutex. Because neither function checks dev->going_away (unlike
input_open_device()), input_uninhibit_device() proceeds to call
dev->open() and start polling on a device that is in the middle of being
unregistered and torn down.
Fix this by checking dev->going_away in input_inhibit_device() and
input_uninhibit_device() under dev->mutex and returning -ENODEV if the
device is going away.

When registering an input handle, handler->start() is currently called
immediately. However, the input device might not be fully opened or
ready to process events at this stage, meaning any state synchronization
events (like setting LED states) injected by the handler's start method
might be dropped.
Move the handler->start() invocation to input_open_device(). If it is
the first handle opening the device, start() is called after the driver's
open() method has successfully completed and the device is fully prepared.
To facilitate this, factor out the device startup logic (calling driver's
open and starting polling) into input_start_device().
For passive observer handlers, their start() method is also deferred
until the handle is opened. Since opening a passive observer handle does
not start the underlying hardware device, their start() method is called
immediately upon opening, regardless of whether the device is active.

When an input device is inhibited via input_inhibit_device(), the driver
is closed and physical feedback (like LEDs and sounds) is toggled off.
However, from the input core's perspective, the handles remain open.
When the device is later uninhibited, the driver is re-opened. While the
core restores simple LED states via input_dev_toggle(), complex handlers
(such as vt/keyboard) may need to re-synchronize their broader logical
state with the hardware.

When uninhibiting a device, we previously called dev->open() and started
the poller before clearing dev->inhibited. Since drivers (like
gpio_keys) often report initial state during open(), and pollers report
events immediately upon starting, these initial events were dropped by
input_get_disposition() because dev->inhibited was still true.
Fix this by clearing dev->inhibited before calling dev->open(), ensuring
initial events are delivered to handlers, and restoring dev->inhibited =
true if dev->open() fails.

When a device is opened via input_open_device(), the driver's open()
callback is invoked. Some drivers, like cm109, submit URBs or perform
other hardware initialization in their open() callbacks.
However, the input core does not prevent dev->event() from being called
concurrently during the driver's open() execution. For instance, if a
console beep occurs, the kbd handler might inject an EV_SND event. This
can lead to double list_add BUGs if the driver submits the same URB in
both open() and event() paths without adequate synchronization.
To fix this, introduce a ready flag in the input_dev structure.
For complex devices (where dev->open is defined), this flag is set to true
only after the driver's open() method successfully completes. The core now
checks ready in input_event_dispose() and input_dev_toggle()
to prevent events from reaching the hardware before it is fully prepared.
For simple devices (no open callback), events are delivered immediately.
We also replay the logical state in input_open_device() by calling
input_dev_toggle() right after marking the device ready, ensuring no
events are permanently lost.
In the inhibit path, we ensure that physical feedback (LEDs/sounds) is
turned off before the device is closed, and we synchronize the inhibited
state transition under the event lock to prevent races with incoming events.

Instead of hardcoding PA-RISC specific keycode tables into atkbd via
compile-time inclusion, have the gscps2 PS/2 port driver attach a
linux,keymap software node device property to the serio device when
a keyboard port is registered. This allows atkbd to dynamically fetch
and apply the custom keymap when probing the port using generic
firmware property helpers, removing architecture-specific hacks from
generic keyboard driver code.
Co-locate the keymap definitions with the serio port driver by moving
hpps2atkbd.h from drivers/input/keyboard/ to drivers/input/serio/.
To handle the five conflicting keys on RDI PrecisionBook laptops without
runtime model string checks or duplicate keymap tables in memory, add
CONFIG_SERIO_GSCPS2_RDI_KEYCODES to drivers/input/serio/Kconfig and
resolve the conflicting keycodes at compile time via preprocessor
macros.

userspace.
Add a 'report_error' field to struct f54_data to store the worker's exit
