The same with all other patches for IRQF_ONESHOT which are send recently:
1. On what board did you test it?
2. Is this just blind patch from Coccinelle without investigation
whether it is needed (hint: it might not be needed in all of these
places, because at least some of them do not use default primary handler).
3. If you think otherwise, please explain.

Best regards,
Krzysztof
