Merge tag 'tty-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty/serial driver updates from Greg KH:
 "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"
