From ca743f701febb6e76ed0894e564044afc78157c4 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Thu, 19 Jun 2014 09:40:30 +0200 Subject: [PATCH] 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 Acked-by: Kuninori Morimoto Signed-off-by: Mark Brown (cherry picked from commit cd7bcc6000165f6215d15e2e32b58a646e5de5ec) Signed-off-by: Simon Horman --- sound/soc/sh/rcar/core.c | 2 +- sound/soc/sh/rcar/rsnd.h | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/sound/soc/sh/rcar/core.c b/sound/soc/sh/rcar/core.c index 6d826c4..bcb2059 100644 --- a/sound/soc/sh/rcar/core.c +++ b/sound/soc/sh/rcar/core.c @@ -365,7 +365,7 @@ int rsnd_dma_init(struct rsnd_priv *priv, struct rsnd_dma *dma, if (ret < 0) goto rsnd_dma_init_err; - dma->dir = is_play ?
