Merge tag 'tty-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial updates from Greg KH:
"Here is the big tty/serial driver update for 4.14-rc1.
Well, not all that big, just a number of small serial driver fixes,
and a new serial driver. Also in here are some much needed goldfish
tty driver (emulator) fixes to try to get that codebase under control.
All of these have been in linux-next for a while with no reported
issues"
