Merge tag 'staging-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging driver tree update from Greg Kroah-Hartman:
"Here's the big staging driver tree update for 3.10-rc1
This update contains loads of comedi driver cleanups and fixes in
here, iio updates, android driver changes, and other various staging
driver cleanups.
Thanks to some drivers being removed, and the comedi driver cleanups,
we have removed more code than we added:
627 files changed, 65145 insertions(+), 76321 deletions(-)
which is always nice to see.
All of these have been in linux-next for a while."
