Yeah, and only that makes sense, if you ask me. And as you said in the
other mail, adding a module name disambiguation policy in userspace
would mean that two different modules would be allowed to both request
the firmware key "foobar" and not have a problem, while it would be
pretty hard to support it with the built-in firmware option.
