Merge tag 'tty-4.20-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty/serial fix from Greg KH:
 "Here is a single fix, a revert, for the 8250 serial driver to resolve
  a reported problem.

  There was some attempted patches to fix the issue, but people are
  arguing about them, so reverting the patch to revert back to the 4.19
  and older behavior is the best thing to do at this late in the release
  cycle.

  The revert has been in linux-next with no reported issues"
