From ddba7fa4cfd16b10adcbe24fa1d3b7de470af863 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 15 Oct 2016 16:55:50 +0200 Subject: ASoC: constify snd_soc_ops structures Check for snd_soc_ops structures that are only stored in the ops field of a snd_soc_dai_link structure. This field is declared const, so snd_soc_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_soc_ops i@p = { ... }; @ok1@ identifier r.i; struct snd_soc_dai_link e; position p; @@ e.ops = &i@p; @ok2@ identifier r.i, e; position p; @@ struct snd_soc_dai_link e[] = { ..., { .ops = &i@p, }, ..., }; @bad@ position p != {r.p,ok1.p,ok2.p}; identifier r.i; struct snd_soc_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct snd_soc_ops i = { ... }; // The effect on the layout of the .o files is shown by the following output of the size command, first before then after the transformation: text data bss dec hex filename 8748 1024 0 9772 262c sound/soc/fsl/fsl-asoc-card.o 8812 952 0 9764 2624 sound/soc/fsl/fsl-asoc-card.o text data bss dec hex filename 4165 264 8 4437 1155 sound/soc/fsl/imx-wm8962.o 4229 200 8 4437 1155 sound/soc/fsl/imx-wm8962.o Signed-off-by: Julia Lawall Signed-off-by: Mark Brown --- sound/soc/fsl/fsl-asoc-card.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sound/soc/fsl/fsl-asoc-card.c') diff --git a/sound/soc/fsl/fsl-asoc-card.c b/sound/soc/fsl/fsl-asoc-card.c index dffd549..9998aea 100644 --- a/sound/soc/fsl/fsl-asoc-card.c +++ b/sound/soc/fsl/fsl-asoc-card.c @@ -183,7 +183,7 @@ static int fsl_asoc_card_hw_params(struct snd_pcm_substream *substream, return 0; } -static struct snd_soc_ops fsl_asoc_card_ops = { +static const struct snd_soc_ops fsl_asoc_card_ops = { .hw_params = fsl_asoc_card_hw_params, }; -- cgit v1.1
