Merge tag 'staging-5.2-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 update for 5.2-rc1.

  Lots of tiny fixes all over the staging and IIO driver trees here,
  along with some new IIO drivers.

  The "counter" subsystem was added in here as well, as it is needed by
  the IIO drivers and subsystem.

  Also we ended up deleting two drivers, making this pull request remove
  a few hundred thousand lines of code, always a nice thing to see. Both
  of the drivers removed have been replaced with "real" drivers in their
  various subsystem directories, and they will be coming to you from
  those locations during this merge window.

  There are some core vt/selection changes in here, that was due to some
  cleanups needed for the speakup fixes. Those have all been acked by
  the various subsystem maintainers (i.e. me), so those are ok.

  We also added a few new drivers, for some odd hardware, giving new
  developers plenty to work on with basic coding style cleanups to come
  in the near future.

  Other than that, nothing unusual here.

  All of these have been in linux-next for a while with no reported
  issues, other than an odd gcc warning for one of the new drivers that
  should be fixed up soon"

[ I fixed up the warning myself  - Linus ]
