Merge tag 'staging-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging / iio updates from Greg KH:
 "Here is the big staging and iio set of patches for the 5.5-rc1
  release.

  It's the usual huge collection of cleanup patches all over the
  drivers/staging/ area, along with a new staging driver, and a bunch of
  new IIO drivers as well.

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