Merge tag 'tty-3.11-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 merge for 3.11-rc1.

  It's not all that big, nothing major changed in the tty api, which is
  a nice change, just a number of serial driver fixes and updates and
  new drivers, along with some n_tty fixes to help resolve some reported
  issues.

  All of these have been in the linux-next releases for a while, with
  the exception of the last revert patch, which was reported this past
  weekend by two different people as being needed."
