#     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"
