…rnel/git/gregkh/staging into next

Pull staging driver updates from Greg KH:
 "Here is the big staging driver pull request for 3.16-rc1.

  Lots of stuff here, tons of cleanup patches, a few new drivers, and
  some removed as well, but I think we are still adding a few thousand
  more lines than we remove, due to the new drivers being bigger than
  the ones deleted.

  One notible bit of work did stand out, Jes Sorensen has gone on a
  tear, fixing up a wireless driver to be "more sane" than it originally
  was from the vendor, with over 500 patches merged here.  Good stuff,
  and a number of users laptops are better off for it.

  All of this has been in linux-next for a while"
