Merge tag 'tty-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty / serial updates from Greg KH:
 "Here is the big set of tty and serial driver patches for 5.14-rc1.

  A bit more than normal, but nothing major, lots of cleanups.
  Highlights are:

   - lots of tty api cleanups and mxser driver cleanups from Jiri

   - build warning fixes

   - various serial driver updates

   - coding style cleanups

   - various tty driver minor fixes and updates

   - removal of broken and disable r3964 line discipline (finally!)

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