Merge tag 'tty-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial updates from Greg KH: "Here is the big TTY / Serial driver merge for 3.11-rc1. It's not all that big, nothing major changed in the tty api, which is a nice change, just a number of serial driver fixes and updates and new drivers, along with some n_tty fixes to help resolve some reported issues.
