The Samsung dmaengine ASoC driver is used with two different dmaengine drivers. The pl80x, which properly supports residue reporting and the pl330, which reports that it does not support residue reporting. So there is no need to manually set the NO_RESIDUE flag. This has the advantage that a proper (race condition free) PCM pointer() implementation is used when the pl80x driver is used. Also once the pl330 driver supports residue reporting the ASoC PCM driver will automatically start using it.
