Merge tag 'staging-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging and IIO driver updates from Greg KH:
 "Here is the big staging/iio driver update for 5.4-rc1.

  Lots of churn here, with a few driver/filesystems moving out of
  staging finally:

     - erofs moved out of staging

     - greybus core code moved out of staging

  Along with that, a new filesytem has been added:

     - extfat

  to provide support for those devices requiring that filesystem (i.e.
  transfer devices to/from windows systems or printers)

  Other than that, there a number of new IIO drivers, and lots and lots
  and lots of staging driver cleanups and minor fixes as people continue
  to dig into those for easy changes.

  All of these have been in linux-next for a while with no reported
  issues"
