From 251fc7a58eca13e4af385cc6458b5533596ddb10 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 15 Oct 2016 16:55:48 +0200 Subject: [PATCH] ASoC: qcom: storm: 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 file is shown by the following output of the size command, first before then after the transformation: text data bss dec hex filename 1420 512 0 1932 78c sound/soc/qcom/storm.o 1484 456 0 1940 794 sound/soc/qcom/storm.o Signed-off-by: Julia Lawall Signed-off-by: Mark Brown --- sound/soc/qcom/storm.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sound/soc/qcom/storm.c b/sound/soc/qcom/storm.c index 2d833bffdba0..8fcac2ac3aa6 100644 --- a/sound/soc/qcom/storm.c +++ b/sound/soc/qcom/storm.c @@ -58,7 +58,7 @@ static int storm_ops_hw_params(struct snd_pcm_substream *substream, return 0; } -static struct snd_soc_ops storm_soc_ops = { +static const struct snd_soc_ops storm_soc_ops = { .hw_params = storm_ops_hw_params, }; -- 2.20.1
