Merge tag 'staging-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging and IIO updates from Greg KH:
"Here is the big staging/iio driver patches for 5.6-rc1
Included in here are:
- lots of new IIO drivers and updates for that subsystem
- the usual huge quantity of minor cleanups for staging drivers
- removal of the following staging drivers:
- isdn/avm
- isdn/gigaset
- isdn/hysdn
- octeon-usb
- octeon ethernet
Overall we deleted far more lines than we added, removing over 40k of
old and obsolete driver code.
All of these changes have been in linux-next for a while with no
reported issues"
