AFAICT this isn't a result of the code unification but rather is a case of the code unification mirroring exactly the pre-merge state. It's all pre-git but my best guess would be that the ASoC version was done before the DMA API was introduced - I expect the ASoC variant ought to be updated to use the DMA API but I've not looked closely enough to be certain.
