Merge tag 'staging-3.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging driver fixes from Greg KH:
 "Here are a number (lots, I know) of fixes for staging drivers to
  resolve a bunch of reported issues.

  The largest patches here is one revert of a patch that is in 3.14-rc1
  to fix reported problems, and a sync of a usb host driver that
  required some ARM patches to go in before it could be accepted (which
  is why it missed -rc1)

  All of these have been in linux-next for a while with no reported
  issues"
