Merge tag 'tty-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty/serial driver updates from Greg KH:
 "Here's the big tty/serial driver update for 3.13-rc1.

  There's some more minor n_tty work here, but nothing like previous
  kernel releases.  Also some new driver ids, driver updates for new
  hardware, and other small things.

  All of this has been in linux-next for a while with no issues"
