Merge tag 'staging-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging tree update from Greg Kroah-Hartman:
 "Here is the big staging tree update for the 3.7-rc1 merge window.

  There are a few patches in here that are outside of the staging area,
  namely HID and IIO patches, but all of them have been acked by the
  relevant subsystem maintainers.  The IIO stuff is still coming in
  through this tree as it hasn't entirely moved out of the staging tree,
  but is almost there.

  Other than that, there wa a ton of work on the comedi drivers to make
  them more readable and the correct style.  Doing that removed a lot of
  code, but we added a new driver to the staging tree, so we didn't end
  up with a net reduction this time around:

   662 files changed, 51649 insertions(+), 26582 deletions(-)

  All of these patches have been in the linux-next tree already.

  Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"
