The drivers/power/domain/power-domain-uclass.c should handle empty implementation of request/rfree callback in exactly the commit you reference above.

Yes, but drivers/reset/reset-uclass.c doesn't and you also removed the request/rfree callbacks for that part of the apple_pmgr driver.

Ah, sigh. Would it rather make sense to change the reset uclass ? It would reduce the amount of empty callbacks.

Maybe. But that should probably done as a single sweep like you did for the power domains. Let's fix this crash first.

Try: [PATCH] reset: Return 0 if ops unimplemented and remove empty functions
If this patch gets applied first, then please make sure it is also un-applied once the above is applied, so we don't grow useless empty functions again.
