Pull tty fix from Greg KH:
 "Here is a single tty core revert for a patch that was reported to
  cause problems.

  The original issue is one that we have lived with for decades, so
  trying to scramble to fix the fix in time for 4.11-final does not make
  sense due to the fragility of the tty ldisc layer. Just reverting it
  makes sense for now"
