Merge tag 'tty-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty/serial updates from Greg KH:
 "Here is the "big" set of tty/serial driver patches for 5.2-rc1.

  It's really pretty small, not much happening in this portion of the
  kernel at the moment. When the "highlight" is the movement of the
  documentation from .txt to .rst files, it's a good merge window.

  There's a number of small fixes and updates over the various serial
  drivers, and a new "tty null" driver for those embedded systems that
  like to make things even smaller and not break things.

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