    Pull staging driver updates from Greg KH:
     "Here is the big staging driver pull request for 4.6-rc1.
    
      Lots of little things here, over 1600 patches or so.  Notable is all
      of the good Lustre work happening, those developers have finally woken
      up and are cleaning up their code greatly.  The Outreachy intern
      application process is also happening, which brought in another 400 or
      so patches.  Full details are in the very long shortlog.
    
      All of these have been in linux-next with no reported issues"
