reported by string_choices.cocci:

Thanks for submitting this!

So "silence a warning" isn't really a great argument for *why* this is
being done.

I wasn't actually familiar with str_enabled_disabled, and initially
this change felt a bit arbitrary: The length of the function name
barely saves code characters - and it only seems to make the logic a
little less readable - so what is the point?

But after digging around it seems the benefit comes from allowing the
"enabled" and "disabled" string constants to be consolidated across
numerous uses. Which saves memory and makes sense.

So it might be good to add some detail in the commit message about
that, just so it's clear why this change is helpful.

Otherwise,
