From 115c7254882ceb965deb05510128464fef06fbfb Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 8 Sep 2016 02:35:23 +0200 Subject: ASoC: constify snd_pcm_ops structures Check for snd_pcm_ops structures that are only stored in the ops field of a snd_soc_platform_driver structure or passed as the third argument to snd_pcm_set_ops. The corresponding field or parameter is declared const, so snd_pcm_ops structures that have this property can be declared as const also. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @r disable optional_qualifier@ identifier i; position p; @@ static struct snd_pcm_ops i@p = { ... }; @ok1@ identifier r.i; struct snd_soc_platform_driver e; position p; @@ e.ops = &i@p; @ok2@ identifier r.i; expression e1, e2; position p; @@ snd_pcm_set_ops(e1, e2, &i@p) @bad@ position p != {r.p,ok1.p,ok2.p}; identifier r.i; struct snd_pcm_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct snd_pcm_ops i = { ... }; // Signed-off-by: Julia Lawall Signed-off-by: Mark Brown --- sound/soc/fsl/fsl_asrc_dma.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sound/soc/fsl') diff --git a/sound/soc/fsl/fsl_asrc_dma.c b/sound/soc/fsl/fsl_asrc_dma.c index ffc000bc1f15..dc30d780f874 100644 --- a/sound/soc/fsl/fsl_asrc_dma.c +++ b/sound/soc/fsl/fsl_asrc_dma.c @@ -322,7 +322,7 @@ static snd_pcm_uframes_t fsl_asrc_dma_pcm_pointer(struct snd_pcm_substream *subs return bytes_to_frames(substream->runtime, pair->pos); } -static struct snd_pcm_ops fsl_asrc_dma_pcm_ops = { +static const struct snd_pcm_ops fsl_asrc_dma_pcm_ops = { .ioctl = snd_pcm_lib_ioctl, .hw_params = fsl_asrc_dma_hw_params, .hw_free = fsl_asrc_dma_hw_free, -- cgit v1.2.3
