Merge tag 'staging-4.21-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 pull request for 4.21-rc1.

  Lots and lots of tiny patches here, nothing major at all. Which is
  good, tiny cleanups is nice to see. No new huge driver removal or
  addition, this release cycle, although there are lots of good IIO
  driver changes, addtions, and movement from staging into the "real"
  part of the kernel, which is always great.

  Full details are in the shortlog, and all of these have been in
  linux-next for a while with no reported issues"
