Ok, sounds good. Note that there may be users of the plain __setup() that
just get turned into nops right now. Usually those are already enclosed in
"#ifndef MODULE", but if they are not, then removing the definition would cause
a build error.

Have a look if you can find such instances, and either change the patch to
add the missing "#ifndef MODULE" checks, or just drop the __setup_param()
and leave the __setup() if it gets too complicated.
