Merge tag 'tty-4.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty/serial fixes from Greg KH:
 "Here are some small fixes for some serial drivers and Kconfig help
  text for 4.11-rc5. Nothing major here at all, a few things resolving
  reported bugs in some random serial drivers.

  I don't think these made the last linux-next due to me getting to them
  yesterday, but I am not sure, they might have snuck in. The patches
  only affect drivers that the maintainers of sent me these patches for,
  so we should be safe here :)"
