Linmao Li 2b3a5dabe8 platform/surface: acpi-notify: Check ACPI companion before use
Since every platform driver can be forced to match a device that doesn't
match its list of device IDs because of device_match_driver_override(),
platform drivers that rely on the existence of a device's ACPI companion
object should verify its presence.

san_probe() dereferences the result of ACPI_COMPANION() when installing
the GSBUS address space handler, so force-binding the driver to a device
without an ACPI companion leads to a NULL pointer dereference.  The
dereference was introduced when the probe function was switched from
ACPI_HANDLE() to ACPI_COMPANION().

Check the ACPI companion against NULL and return -ENODEV when it is
missing, like commit e4865a56d0 ("ACPI: driver: Check ACPI_COMPANION()
against NULL during probe") does for the core ACPI platform drivers.

Rafael J. Wysocki 57de5fb319 platform/surface: surfacepro3_button: Stop setting acpi_device_name()
The driver sets acpi_device_name() to initialize an input class device
name initialization and print a message on probe success, but the input
class device name can be set directly to the "Surface Pro 3/4 Buttons"
string literal and used for printing the message.

Make the driver do so, stop setting acpi_device_name() in it and drop
the symbol specifically defined for this purpose.

No intentional functional impact.

This will facilitate the removal of device_name from struct
acpi_device_pnp in the future.

Uwe Kleine-König (The Capable Hub) 613550ffe3 platform/surface: aggregator: Consistently define ssam_device_ids using named initializers
The .driver_data member of the the two struct ssam_device_id arrays were
initialized by list expressions. This isn't easily readable if you don't
work with the Surface System Aggregator core regularily. Using named
initializers is more explicit and thus easier to parse and also more
robust to changes of the struct definition. This robustness is relevant
for a planned change to struct ssam_device_id replacing .driver_data
by an anonymous union.

This change doesn't introduce changes to the compiled ssam_device_id
arrays.

Rafael J. Wysocki d913a5a12b platform/surface: surfacepro3_button: Convert to a platform driver
In all cases in which a struct acpi_driver is used for binding a driver
to an ACPI device object, a corresponding platform device is created by
the ACPI core and that device is regarded as a proper representation of
underlying hardware.  Accordingly, a struct platform_driver should be
used by driver code to bind to that device.  There are multiple reasons
why drivers should not bind directly to ACPI device objects [1].

Overall, it is better to bind drivers to platform devices than to their
ACPI companions, so convert the Surface Pro 3 button ACPI driver to a
platform one.

After this change, the subordinate input device and wakeup source class
device will be registered under the platform device used for driver
binding instead of its ACPI companion.

While this is not expected to alter functionality, it changes sysfs
layout and so it will be visible to user space.

Linus Torvalds bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

Kees Cook 69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

Marco Crivellari f720239ca3 platform: surface: replace use of system_wq with system_percpu_wq
This patch continues the effort to refactor workqueue APIs, which has begun
with the changes introducing new workqueues and a new alloc_workqueue flag:

   commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
   commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")

The point of the refactoring is to eventually alter the default behavior of
workqueues to become unbound by default so that their workload placement is
optimized by the scheduler.

Before that to happen after a careful review and conversion of each individual
case, workqueue users must be converted to the better named new workqueues with
no intended behaviour changes:

   system_wq -> system_percpu_wq
   system_unbound_wq -> system_dfl_wq

This way the old obsolete workqueues (system_wq, system_unbound_wq) can be
removed in the future.

Marco Crivellari f03dd5dd73 platform/surface: acpi-notify: add WQ_PERCPU to alloc_workqueue users
This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:

   commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
   commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")

The refactoring is going to alter the default behavior of
alloc_workqueue() to be unbound by default.

With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU. For more details see the Link tag below.

In order to keep alloc_workqueue() behavior identical, explicitly request
WQ_PERCPU.

Linus Torvalds e70140ba0d Get rid of 'remove_new' relic from platform driver struct
The continual trickle of small conversion patches is grating on me, and
is really not helping.  Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:

  /*
   * .remove_new() is a relic from a prototype conversion of .remove().
   * New drivers are supposed to implement .remove(). Once all drivers are
   * converted to not use .remove_new any more, it will be dropped.
   */

This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.

I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.

Then I just removed the old (sic) .remove_new member function, and this
is the end result.  No more unnecessary conversion noise.

no_llseek had been defined to NULL two years ago, in commit 868941b144

  At -rc1 we'll need do a mechanical removal of no_llseek -

  git grep -l -w no_llseek | grep -v porting.rst | while read i; do
	sed -i '/\<no_llseek\>/d' $i

  would do it.

Unfortunately, that hadn't been done.  Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
	.llseek = no_llseek,
so it's obviously safe.

- X Elite: Laptop 7 / Pro11

Thankfully, the aggregators on these seem to be configured in an
identical way, which allows for using these settings as defaults and
no DT properties need to be introduced (until that changes, anyway).

Based on the work done by Maximilian Luz, largely rewritten.

Maximilian Luz bc923d594d platform/surface: aggregator: Fix warning when controller is destroyed in probe
There is a small window in ssam_serial_hub_probe() where the controller
is initialized but has not been started yet. Specifically, between
ssam_controller_init() and ssam_controller_start(). Any failure in this
window, for example caused by a failure of serdev_device_open(),
currently results in an incorrect warning being emitted.

In particular, any failure in this window results in the controller
being destroyed via ssam_controller_destroy(). This function checks the
state of the controller and, in an attempt to validate that the
controller has been cleanly shut down before we try and deallocate any
resources, emits a warning if that state is not SSAM_CONTROLLER_STOPPED.

However, since we have only just initialized the controller and have not
yet started it, its state is SSAM_CONTROLLER_INITIALIZED. Note that this
is the only point at which the controller has this state, as it will
change after we start the controller with ssam_controller_start() and
never revert back. Further, at this point no communication has taken
place and the sender and receiver threads have not been started yet (and
we may not even have an open serdev device either).

Therefore, it is perfectly safe to call ssam_controller_destroy() with a
state of SSAM_CONTROLLER_INITIALIZED. This, however, means that the
warning currently being emitted is incorrect. Fix it by extending the
check.
