So, this is pretty fun and probably not going to play too nicely for multiplatform kernels...
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.
