Ironically, it's the only "WARNING" while the rest are "ERRORS".
OTOH I personally believe all output from checkpatch should be labeled
"WARNING"; it's not for checkpatch to decide. It's only a tool.

Actually, I think it wasn't any issue at all at this point, when it
wasn't yet established if the patch makes sense at all.

You apparently forgot what SubmittingPatches file is all about:

"This text is a collection of suggestions which can greatly increase the
chances of your change being accepted."

You know, we don't have laws for everything here. And we're not
androids specialized in producing C code. We are supposed to use some
common sense first.

That's true, though it's the same for "staging".
