From: Julia Lawall Date: Sat, 15 Oct 2016 14:55:45 +0000 (+0200) Subject: ASoC: intel: broadwell: constify snd_soc_ops structures X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d5bc18c148fd3d3ab7cbd3d976f7e27226f74dd8;p=linux-beck.git ASoC: intel: broadwell: 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 3865 2784 384 7033 1b79 sound/soc/intel/boards/broadwell.o 3929 2720 384 7033 1b79 sound/soc/intel/boards/broadwell.o Signed-off-by: Julia Lawall Acked-by: Jie Yang Signed-off-by: Mark Brown --- diff --git a/sound/soc/intel/boards/broadwell.c b/sound/soc/intel/boards/broadwell.c index 7486a0022fde..5bb64d164877 100644 --- a/sound/soc/intel/boards/broadwell.c +++ b/sound/soc/intel/boards/broadwell.c @@ -126,7 +126,7 @@ static int broadwell_rt286_hw_params(struct snd_pcm_substream *substream, return ret; } -static struct snd_soc_ops broadwell_rt286_ops = { +static const struct snd_soc_ops broadwell_rt286_ops = { .hw_params = broadwell_rt286_hw_params, };
