Pull tty/serial updates from Greg KH:
 "Here is the "big" TTY/Serial patch updates for 4.12-rc1

  Not a lot of new things here, the normal number of serial driver
  updates and additions, tiny bugs fixed, and some core files split up
  to make future changes a bit easier for Nicolas's "tiny-tty" work.

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