Merge tag 'staging-5.12-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging and IIO driver fixes from Greg KH:
"Some small staging and IIO driver fixes:
- MAINTAINERS changes for the move of the staging mailing list
- comedi driver fixes to get request_irq() to work correctly
- counter driver fixes for reported issues with iio devices
- tiny iio driver fixes for reported issues.
All of these have been in linux-next with no reported problems"
