Pull tty / serial driver updates from Greg KH:
"Here is the big set of tty and serial driver updates for 5.16-rc1.

Nothing major in here at all, just lots of tiny serial and tty driver
updates for various reported things, and some good cleanups. These
include:

- more good tty api cleanups from Jiri

- stm32 serial driver updates

- softlockup fix for non-preempt systems under high serial load

- rpmsg serial driver update

- 8250 drivers updates and fixes

- n_gsm line discipline fixes and updates as people are finally
starting to use it.

All of these have been in linux-next for a while now with no reported
issues"

Pull tty and serial driver updates from Greg KH:
"Here is the big set of tty and serial driver updates for 5.13-rc1.

Actually busy this release, with a number of cleanups happening:

- much needed core tty cleanups by Jiri Slaby

- removal of unused and orphaned old-style serial drivers. If anyone
shows up with this hardware, it is trivial to restore these but we
really do not think they are in use anymore.

- fixes and cleanups from Johan Hovold on a number of termios setting
corner cases that loads of drivers got wrong as well as removing
unneeded code due to tty core changes from long ago that were never
propagated out to the drivers

- loads of platform-specific serial port driver updates and fixes

- coding style cleanups and other small fixes and updates all over
the tty/serial tree.

All of these have been in linux-next for a while now with no reported
issues"

serial: sifive: drop low-latency workaround

The sifive driver has always carried an unnecessary workaround for the
infamous low_latency behaviour of tty_flip_buffer_push() which had been
removed years before the driver was added by commit 45c054d0815b ("tty:
serial: add driver for the SiFive UART").

Specifically, since commit a9c3f68f3cd8 ("tty: Fix low_latency BUG"),
tty_flip_buffer_push() always schedules a work item to push data to the
line discipline and there's no need to keep any low_latency hacks around.
