Well, the thing here is more about the fact that the match function is silently being hijacked - it should be possible to do this in the device registrations. I'd expect you could get a non-DT kernel which was affected, but you'd probably have to try. > Anyway, I would happily redesign and rewrite the DMA engine channel > matching completely to make it much more sane, but I guess I would need an > ack from Vinod and Dan to do it. I'd be really keen to get this code merged sooner rather than later for ASoC development so if there's a way to do it separately to fixing the filtering that'd be good.
