Merge tag 'staging-5.3-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 5.3-rc1.
Lots of new IIO drivers are in here, along with loads of tiny staging
driver cleanups and fixes. Overall we almost break even with the same
lines added as removed.
Full details are in the shortlog, they are too large to list here.
All of these changes have been in linux-next for a while with no
reported issues"
