Pull tty/serial driver fixes from Greg KH:
"Here are some small tty core and serial driver fixes for 4.16-rc6.
They resolve some newly reported bugs, as well as some very old ones,
which is always nice to see. There is also a new device id added in
here for good measure.
All of these have been in linux-next for a while with no reported
issues"
