Merge tag 'staging-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull rtl8812ae staging wireless driver from Greg KH:
 "Here's a single staging driver for a wireless chipset that has shown
  up in the SteamBox hardware.  It is merged separately from the "main"
  staging pull request to sync up with the wireless api changes that
  came in from the networking tree.

  It's self-contained and works for me and others.  Larry will be
  replacing it with a "real" driver for 3.15, but for now this one is
  needed"
