Did you test it? There are several patches like this all over the tree
so it looks like "let's fix everything from Coccinelle" because you
ignored at least in some of the cases that the handler is not the
default primary one. I am not saying that the change is bad, but
rather it looks automated and needs more consideration.
Best regards,
Krzysztof
