Well, duh. Maybe they shouldn't be marked "inline", and maybe they should
be marked with "__maybe_unused" instead.

I do not think it makes sense to use "inline" as a way to say "maybe I
won't use this function".

Yes, it's true that "static inline" won't warn, but hey, as a way to avoid
a warning it's a pretty bad one.
