Merge tag 'staging-4.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging and IIO driver fixes from Greg KH:
"Here are some small staging and iio driver fixes for reported issues
for 4.9-rc3. Nothing major, the "largest" being a lustre fix for a
sysfs file that was obviously wrong, and had never been tested, so it
was moved to debugfs as that is where it belongs. The others are small
bug fixes for reported issues with various staging or iio drivers.
All have been in linux-next for a while with no reported issues"
