Merge tag 'staging-4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging/iio driver updates from Greg KH:
 "Here is the big staging and iio driver patchsets for 4.11-rc1.

  We almost broke even this time around, with only a few thousand lines
  added overall, as we removed the old and obsolete i4l code, but added
  some new drivers for the RPi platform, as well as adding some new IIO
  drivers.

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