Merge tag 'tty-3.3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull TTY/serial patches from Greg KH:
"tty and serial merge for 3.4-rc1
Here's the big serial and tty merge for the 3.4-rc1 tree.
There's loads of fixes and reworks in here from Jiri for the tty
layer, and a number of patches from Alan to help try to wrestle the vt
layer into a sane model.
Other than that, lots of driver updates and fixes, and other minor
stuff, all detailed in the shortlog."
