serial: core: Keep mctrl register state and cached copy in sync (2022-01-06 16:01:48 +0100)
----------------------------------------------------------------
TTY/Serial driver updates for 5.17-rc1
Here is the big set of tty/serial driver updates for 5.17-rc1.
Nothing major in here, just lots of good updates and fixes, including:
- more tty core cleanups from Jiri as well as mxser driver
cleanups. This is the majority of the core diffstat
- tty documentation updates from Jiri
- platform_get_irq() updates
- various serial driver updates for new features and hardware
- fifo usage for 8250 console, reducing cpu load a lot
- LED fix for keyboards, long-time bugfix that went through many
revisions
- minor cleanups
All have been in linux-next for a while with no reported problems.
