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.
