Merge tag 'staging-3.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging tree merge from Greg KH:
"Here's the bit staging tree pull request for 3.12-rc1.
Lots of staging driver updates, and fixes. Lustre is finally enabled
in the build, and lots of cleanup started happening in it. There's a
new wireless driver in here, and 2 new TTY drivers, which cause the
overall lines added/removed to be quite large on the "added" side.
The IIO driver updates are also coming through here, as they are tied
to the staging iio drivers"
