Merge tag 'bus_remove_return_void-5.15' into next

This helps to remove conflict on idxd driver

 Conflicts:
	drivers/dma/idxd/sysfs.c
	drivers/dma/idxd/bus.c

Greg says:

Bus: Make remove callback return void tag

Tag for other trees/branches to pull from in order to have a stable
place to build off of if they want to add new busses for 5.15.
