Merge tag 'tty-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty/serial updates from Greg KH:
 "Here is the big tty/serial driver update for 4.18-rc1.

  There's nothing major here, just lots of serial driver updates. Full
  details are in the shortlog, nothing anything specific to call out
  here.

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