Merge tag 'tty-3.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial driver patches from Greg KH:
"Here's the big tty/serial driver pull request for 3.12-rc1.
Lots of n_tty reworks to resolve some very long-standing issues,
removing the 3-4 different locks that were taken for every character.
This code has been beaten on for a long time in linux-next with no
reported regressions.
Other than that, a range of serial and tty driver updates and
revisions. Full details in the shortlog"
