Merge tag 'tty-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty / serial driver update from Greg KH:
 "Here's the big tty / serial driver update for 3.17-rc1.

  Nothing major, just a number of fixes and new features for different
  serial drivers, and some more tty core fixes and documentation of the
  tty locks.

  All of these have been in linux-next for a while"
