Merge tag 'tty-3.18-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 patchset for 3.18-rc1.
Lots of little things in here, some good work from Peter Hurley on the
tty core, and in lots of drivers. There are also lots of other driver
updates in here as well, full details in the changelogs.
All have been in the linux-next tree for a while"
