Merge tag 'staging-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging and IIO driver updates from Greg KH:
 "Here's the big staging and iio driver update for 4.7-rc1.

  I think we almost broke even with this release, only adding a few more
  lines than we removed, which isn't bad overall given that there's a
  bunch of new iio drivers added.

  The Lustre developers seem to have woken up from their sleep and have
  been doing a great job in cleaning up the code and pruning unused or
  old cruft, the filesystem is almost readable :)

  Other than that, just a lot of basic coding style cleanups in the
  churn.  All have been in linux-next for a while with no reported
  issues"
