Main purpose of .nolock_start is we need to call some function without spinlock. OTOH we have .prepare which main purpose is called under atomic context. Then, it is called without spinlock. In summary, our main callback init/quit, and start/stop are called under "atomic context and with spinlock". And some function need to be called under "non-atomic context or without spinlock". Let's merge .nolock_start and prepare to be more clear code. Then, let's rename nolock_stop to cleanup Signed-off-by: Kuninori Morimoto Tested-by: Hiroyuki Yokoyama Signed-off-by: Mark Brown Signed-off-by: Biju Das --- sound/soc/sh/rcar/core.c | 13 ++----------- sound/soc/sh/rcar/dma.c | 20 ++++++++++---------- sound/soc/sh/rcar/rsnd.h | 26 ++++++++++---------------- 3 files changed, 22 insertions(+), 37 deletions(-) diff --git a/sound/soc/sh/rcar/core.c b/sound/soc/sh/rcar/core.c index 636f6ed..fd41da7 100644 --- a/sound/soc/sh/rcar/core.c +++ b/sound/soc/sh/rcar/core.c @@ -875,12 +875,10 @@ static int rsnd_soc_dai_startup(struct snd_pcm_substream *substream, struct snd_soc_dai *dai) { struct rsnd_dai *rdai = rsnd_dai_to_rdai(dai);
