Merge tag 'staging-4.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging and iio driver fixes from Greg KH:
"Here are a number of small staging and iio driver fixes for reported
issues for 4.15-rc3. Nothing major here, the majority is IIO issues,
like normal, but there are also some small bugfixes for a few staging
drivers as well.
Full details are in the shortlog.
All of these have been in linux-next for a while with no reported
issues"
