So far I've managed to do this with two different approaches, but both of them are broken in some way :-( Couple questions: 1. Is it possible to force two symbols to be both built-in (=y) or both modules (=m)? This would make one of my solutions work. 2. Do you think it's possible to split this as a module *without* requesting the driver dynamically? I've tried the same extensions approach as in em28xx and others, but found some problems with the way snd-usb-audio driver registers.
