Merge tag 'tty-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial driver updates from Greg KH:
"Here's the big tty/serial driver update for 3.19-rc1.
There are a number of TTY core changes/fixes in here from Peter Hurley
that have all been teted in linux-next for a long time now. There are
also the normal serial driver updates as well, full details in the
changelog below"
