Pull tty/serial updates from Greg KH:
 "Here's the tty/serial patchset for 4.10-rc1.

  It's been a quiet kernel cycle for this subsystem, just a small number
  of changes. A few new serial drivers, and some cleanups to the old
  vgacon logic, and other minor serial driver changes as well.

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