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's not needed here, it does not use
default primary handler).
3. If you think otherwise, please explain.

Best regards,
Krzysztof
