Merge tag 'staging-3.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging fixes from Greg Kroah-Hartman:
"Here are a number of small fixes to staging drivers for your 3.8-rc3
tree.
Well, the omapdrm fixes aren't really "small" but they were waiting on
a number of other drm patches to go in through the drm tree, and got
delayed by my vacation over the holidays. They are totally
self-contained, everyone involved have acked them, and they fix issues
that people have been having with the driver.
Other than that one, it's a bunch of tiny bugfixes for a number of
reported issues.
