Merge tag 'staging-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging driver tree merge from Greg Kroah-Hartman:
"Here's the big staging tree merge for 3.8-rc1
There's a lot of patches in here, the majority being the comedi
rework/cleanup that has been ongoing and is causing a huge reduction
in overall code size, which is amazing to watch. We also removed some
older drivers (telephony and rts_pstor), and added a new one (fwserial
which also came in through the tty tree due to tty api changes, take
that one if you get merge conflicts.)
The iio and ipack drivers are moving out of the staging area into
their own part of the kernel as they have been cleaned up sufficiently
and are working well.
Overall, again a reduction of code:
768 files changed, 31887 insertions(+), 82166 deletions(-)
All of this has been in the linux-next tree for a while.
