Merge tag 'staging-4.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging driver updates from Greg KH:
 "Here's the big staging driver update for 4.4-rc1.  If you were
  disappointed for 4.3-rc1 that we didn't contribute enough changesets,
  you should be happy with this pull request of over 2400 patches.

  But overall we removed more lines of code than we added, which is nice
  to see.  Full details in the shortlog.

  All of these have been in linux-next for a while"

Greg, I've never been disappointed in how few commits Staging
contributes to the kernel..  Never.
