KBUILD_MODNAME is not defined for files that are linked into multiple modules, and trying to change reality to match documentation would result in all sorts of trouble. E.g. options for built-in modules would be called either foo_bar.param, foo.param, or bar.param, depending on the configuration. So just change the comment.
