Hi Marc Just a gentleman ping about this patch. I verified, you could always apply this patch on linux master branch.

exti hardware point of view, there is no specific action on set_affinity. So the affinity must be forwarded to parent if there is a descendent irqchips, otherwise just return IRQ_SET_MASK_OK_DONE.
