Yes, this is really funny and only shows the brokenness of current channel 
filtering mechanism used in DMA engine subsystem. Fortunately this is 
quite irrelevant to multiplatform kernels, because no users of it will be 
compiled in, since it's used only for legacy (non-DT) channel filtering.

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.

Best regards,
