Jiri Slaby 28f194da4a tty: make tty_ldisc_ops::hangup return void
The documentation says that the return value of tty_ldisc_ops::hangup
hook is ignored. And it really is, so there is no point for its return
type to be int. Switch it to void and all the hooks too.

Jiri Slaby b34440ffad mxser: Documentation, make the docs up-to-date
Remove all the obsolete information from the documentation of mxser
driver. Either it was about the out-of-tree driver, or it was superseded
by udev et al.

Jiri Slaby 291343676e mxser: drop ISA support
While mxser PCI cards are still around and produced (Moxa provided me
with two recently), ISA cards are obsolete for a long time. I haven't
seen anyone using the cards and the ISA code paths are barely tested.

Hence, remove ISA support from mxser driver so that we can clean the
driver up.

Jiri Slaby 3b00b6af7a tty: rocket, remove the driver
While the driver is still marked as maintained in MAINTAINERS, Comtrol
does not really care about this ancient driver. They are still
manufacturing serial devices, but those are controlled only by
out-of-tree drivers.

Comtrol didn't answer my pings, so this driver is apparently
unmaintained.  Aside from that, the driver was untouched for years, only
whole-tree changes happened during the past years. The driver needs much
more care, so drop it for now. If someone steps up to reintroduce it,
they need to clean it up first.

Jiri Slaby f76edd8f7c tty: cyclades, remove this orphan
The Cyclades driver was orphaned by commit d459883e6c (MAINTAINERS:
remove two dead e-mail) 13 years ago. Noone stepped up to take care of
them and to fix all the issues the driver has.

On the top of that, there is no way to obtain the firmware for Z cards
from the vendor as cyclades.com ceased to exist.

So it's time to drop the driver with all its traces.

Alexander A. Klimov a6fdf0c771 tty: vt: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Martin Hundebøll a7b121b4b8 tty: n_gsm: add ioctl to map serial device to mux'ed tty
Guessing the first tty for a gsm0710 multiplexed serial device is not
currently possible, which makes it racy to use with multiple modems.

Add a way to map the physical serial tty to its related mux devices
using an ioctl.
