ASoC: rcar: Fix dma direction type
dmaengine_prep_slave_single() expects a enum dma_transfer_direction and not a enum dma_data_direction. Since the integer representations of both DMA_TO_DEVICE and DMA_MEM_TO_DEV aswell as DMA_FROM_DEVICE and DMA_DEV_TO_MEM have the same value the code worked fine even though it was using the wrong type. Fixes the following warning from sparse: sound/soc/sh/rcar/core.c:227:49: warning: mixing different enum types sound/soc/sh/rcar/core.c:227:49: int enum dma_data_direction versus sound/soc/sh/rcar/core.c:227:49: int enum dma_transfer_direction Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>
