Merge tag 'staging-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging and IIO driver updates from Greg KH:
"Here is the big Staging and IIO driver update for 4.8-rc1.
We ended up adding more code than removing, again, but it's not all
that bad. Lots of cleanups all over the staging tree, and new IIO
drivers, full details in the shortlog.
All of these have been in linux-next for a while with no reported
issues"
