Staging/IIO driver fixes for 5.12-rc4

Browse Source 
Here are some small staging and IIO driver fixes for 5.12-rc4.
 
 They include:
 	- 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.
