From 705e9994a437bbdaf655612f3526e3567db56bdd Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 15 Oct 2016 16:55:47 +0200 Subject: [PATCH] ASoC: rockchip: 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 5027 2488 416 7931 1efb sound/soc/rockchip/rk3399_gru_sound.o 5219 2312 416 7947 1f0b sound/soc/rockchip/rk3399_gru_sound.o text data bss dec hex filename 3499 1648 384 5531 159b sound/soc/rockchip/rockchip_max98090.o 3563 1584 384 5531 159b sound/soc/rockchip/rockchip_max98090.o text data bss dec hex filename 3455 1536 384 5375 14ff sound/soc/rockchip/rockchip_rt5645.o 3519 1480 384 5383 1507 sound/soc/rockchip/rockchip_rt5645.o Signed-off-by: Julia Lawall Signed-off-by: Mark Brown --- sound/soc/rockchip/rk3399_gru_sound.c | 6 +++--- sound/soc/rockchip/rockchip_max98090.c | 2 +- sound/soc/rockchip/rockchip_rt5645.c | 2 +- 3 files changed, 5 insertions(+), 5 deletions(-) diff --git a/sound/soc/rockchip/rk3399_gru_sound.c b/sound/soc/rockchip/rk3399_gru_sound.c index 0cbd23555ba4..3475c61a5fa0 100644 --- a/sound/soc/rockchip/rk3399_gru_sound.c +++ b/sound/soc/rockchip/rk3399_gru_sound.c @@ -228,15 +228,15 @@ static int rockchip_sound_da7219_init(struct snd_soc_pcm_runtime *rtd) return 0; } -static struct snd_soc_ops rockchip_sound_max98357a_ops = { +static const struct snd_soc_ops rockchip_sound_max98357a_ops = { .hw_params = rockchip_sound_max98357a_hw_params, }; -static struct snd_soc_ops rockchip_sound_rt5514_ops = { +static const struct snd_soc_ops rockchip_sound_rt5514_ops = { .hw_params = rockchip_sound_rt5514_hw_params, }; -static struct snd_soc_ops rockchip_sound_da7219_ops = { +static const struct snd_soc_ops rockchip_sound_da7219_ops = { .hw_params = rockchip_sound_da7219_hw_params, }; diff --git a/sound/soc/rockchip/rockchip_max98090.c b/sound/soc/rockchip/rockchip_max98090.c index e70ffad07184..789d6f1e2b5f 100644 --- a/sound/soc/rockchip/rockchip_max98090.c +++ b/sound/soc/rockchip/rockchip_max98090.c @@ -119,7 +119,7 @@ static int rk_aif1_hw_params(struct snd_pcm_substream *substream, return ret; } -static struct snd_soc_ops rk_aif1_ops = { +static const struct snd_soc_ops rk_aif1_ops = { .hw_params = rk_aif1_hw_params, }; diff --git a/sound/soc/rockchip/rockchip_rt5645.c b/sound/soc/rockchip/rockchip_rt5645.c index 440a8026346a..9e0c17805807 100644 --- a/sound/soc/rockchip/rockchip_rt5645.c +++ b/sound/soc/rockchip/rockchip_rt5645.c @@ -135,7 +135,7 @@ static int rk_init(struct snd_soc_pcm_runtime *runtime) &headset_jack); } -static struct snd_soc_ops rk_aif1_ops = { +static const struct snd_soc_ops rk_aif1_ops = { .hw_params = rk_aif1_hw_params, }; -- 2.30.2
