Merge tag 'tty-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty/serial updates from Greg KH:
 "Here is the big tty/serial driver update for 4.14-rc1.

  Well, not all that big, just a number of small serial driver fixes,
  and a new serial driver. Also in here are some much needed goldfish
  tty driver (emulator) fixes to try to get that codebase under control.

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