Merge tag 'staging-5.2-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging 

Pull staging/IIO/counter fixes from Greg KH:
 "Here are some small driver bugfixes for some staging/iio/counter
  drivers.

  Staging and IIO have been lumped together for a while, as those
  subsystems cross the areas a log, and counter is used by IIO, so
  that's why they are all in one pull request here.

  These are small fixes for reported issues in some iio drivers, the
  erofs filesystem, and a build issue for counter code.

  All have been in linux-next with no reported issues"
