Pull tty/serial driver updates from Greg KH:
"Here's the big tty/serial driver pull request for 3.14-rc1
There are a number of n_tty fixes and cleanups, and some serial driver
bugfixes, and we got rid of one obsolete driver, making this series

All of these have been in linux-next with no reports of issues"
