Yes for dmaengine drivers I do ask this question which typically ends up in

IMHO don't think devm irq calls are very useful, they do make stuff
complicate
Would it be better then to just go back to request_irq (or whatever is
appropriate in this case). It would seem that the devm property can never
be relied on, so there is no point to use it.
Yes I do think that is right way in this case
Hmm, OK, I will drop the patch I submitted removing the explicit
devm_free_irq() call and send a new one which stops using the devm IRQ
functions, and kills the tasklets.
Thanks,
Alex
