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 warnings from sparse: sound/soc/sh/fsi.c:1307:42: warning: mixing different enum types sound/soc/sh/fsi.c:1307:42: int enum dma_data_direction versus sound/soc/sh/fsi.c:1307:42: int enum dma_transfer_direction Signed-off-by: Lars-Peter Clausen Signed-off-by: Mark Brown --- diff --git a/sound/soc/sh/fsi.c b/sound/soc/sh/fsi.c index c76344350e44..66fddec9543d 100644 --- a/sound/soc/sh/fsi.c +++ b/sound/soc/sh/fsi.c @@ -1297,9 +1297,14 @@ static int fsi_dma_transfer(struct fsi_priv *fsi, struct fsi_stream *io) struct snd_pcm_substream *substream = io->substream; struct dma_async_tx_descriptor *desc; int is_play = fsi_stream_is_play(fsi, io); - enum dma_data_direction dir = is_play ?
