Interrupt context can't sleep. Drivers like Panfrost and MSM are taking mutex when job is released, and thus, that code can sleep. This results into "BUG: scheduling while atomic" if locks are contented while job is freed. There is no good reason for releasing scheduler's jobs in IRQ context, hence use normal context to fix the trouble.

Is there something blocking this patch? Mesa CI is still hitting the issue and I have been waiting for it to be applied/backported to update CI with it. Thanks
If this patch won't be picked up anytime soon, then I'll include it into my "memory shrinker" patchset together with the rest of the fixes, so it won't get lost.
