Merge tag 'staging-3.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging tree update from Greg Kroah-Hartman:
"Here's the big staging tree merge for 3.9-rc1
Lots of cleanups and updates for drivers all through the staging tree.
We are pretty much "code neutral" here, adding just about as many
lines as we removed.
All of these have been in linux-next for a while."
