Merge tag 'tty-3.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull TTY fixes from Greg Kroah-Hartman:
"Here are some tty and serial driver fixes for your 3.7-rc1 tree.
Again, the UABI header file fixes, and a number of build and runtime
serial driver bugfixes that solve problems people have been reporting
(the staging driver is a tty driver, hence the fixes coming in through
this tree.)
All of these have been in the linux-next tree for a while.
Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"
