If we didn't load the firmware before the suspend, then the resume
function of a device sure as hell had better not load it at resume
time either.

And don't make the stupid argument that we don't know. That's just
inane. Either the driver loads the firmware at startup, or it doesn't.
If it loads it at startup, the firmware will have been loaded. If it
loads it only at "open" time or similar (and the device wasn't
opened), then the resume had better *know* about that, and not try to
load the firmware of a device that wasn't open!

And for chrissake, don't bother making it more complicated than it is,
just for some theoretical hardware or situation that nobody cares
about.

Go back to the original report of the *actual* problems we have. They
are not some complex case where things magically change. The REAL
ACTUAL problems that people have are for very straightforward
situations where we simply do the wrong thing, largely because our
firmware loading is full of crap.

Fix the 99%. Screw the crazy shit, don't even bother worrying about it
until *after* the 99% is fixed.
