Merge tag 'tty-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty/serial driver patches from Greg KH:
 "Here's the big tty/serial driver update for 3.20-rc1.  Nothing huge
  here, just lots of driver updates and some core tty layer fixes as
  well.  All have been in linux-next with no reported issues"
