Merge tag 'tty-4.11-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 tty/serial driver patchset for 4.11-rc1.

  Not much here, but a lot of little fixes and individual serial driver
  updates all over the subsystem. Majority are for the sh-sci driver and
  platform (the arch-specific changes have acks from the maintainer).

  The start of the "serial bus" code is here as well, but nothing is
  converted to use it yet. That work is still ongoing, hopefully will
  start to show up across different subsystems for 4.12 (bluetooth is
  one major place that will be used.)

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