Merge tag 'tty-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty and serial driver updates from Greg KH:
 "Here's the large TTY and Serial driver update for 4.7-rc1.

  A few new serial drivers are added here, and Peter has fixed a bunch
  of long-standing bugs in the tty layer and serial drivers as normal.
  Full details in the shortlog.

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