Having the firmware files under plfxlc/ directory looks good to me. But
I'm not really a fan of upper case filenames, is there a reason for
that? I would prefer have all lowercase filenames.

Also the cast (const struct firmware **) looks very wrong, but I didn't
investigate why you do it. I'm sure there is a proper way to implement
whatever you need here, without the cast.
