Merge tag 'staging-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging / iio updates from Greg KH:
"Here is the big staging and iio set of patches for the 5.5-rc1
release.
It's the usual huge collection of cleanup patches all over the
drivers/staging/ area, along with a new staging driver, and a bunch of
new IIO drivers as well.
Full details are in the shortlog, but all of these have been in
linux-next for a long time with no reported issues"
