Merge tag 'staging-4.9-rc5' of git://

Pull staging/IIO fixes from Grek KH:
 "Here are a few small staging and iio driver fixes for reported issues.

  The last one was cherry-picked from my -next branch to resolve a build
  warning that Arnd fixed, in his quest to be able to turn
  -Wmaybe-uninitialized back on again. That patch, and all of the
  others, have been in linux-next for a while with no reported issues"
