Merge tag 'tty-5.16-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 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"
