Merge tag 'staging-4.20-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 4.20-rc1.

  There are lots of things here, we ended up adding more lines than
  removing, thanks to a large influx of Comedi National Instrument
  device support. Someday soon we need to get comedi out of staging...

  Other than the comedi drivers, the "big" things here are:

   - new iio drivers

   - delete dgnc driver (no one used it and no one had the hardware
     anymore)

   - vbox driver updates and fixes

   - erofs fixes

   - tons and tons of tiny checkpatch fixes for almost all staging
     drivers

  All of these have been in linux-next, with the last few happening a
  bit "late" due to them getting stuck on my laptop during travel to the
  Mantainers summit"
