Pull staging tree fixes from Greg Kroah-Hartman:
 "Here are some drivers/staging and drivers/iio fixes for 3.9 (the two
  are still pretty intertwined, hence them coming both from my tree
  still.) Nothing major, just a few things that have been reported by
  users, all of these have been in linux-next for a while."
