Merge tag 'staging-5.7-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging/iio fixes from Greg KH:
"Here are some small staging and IIO driver fixes for 5.7-rc7
Nothing major, just a collection of IIO driver fixes for reported
issues, and a few small staging driver fixes that people have found.
Full details are in the shortlog.
All of these have been in linux-next for a while with no reported
issues"
