Merge tag 'tty-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial updates from Greg KH:
"Here is the large tty/serial patchset for 4.13-rc1.
A lot of tty and serial driver updates are in here, along with some
fixups for some __get/put_user usages that were reported. Nothing
huge, just lots of development by a number of different developers,
full details in the shortlog.
All of these have been in linux-next for a while"
