From f802d6c020658b5dce1732da0d5999a1a65afdd6 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 31 Aug 2016 23:52:27 +0200 Subject: ASoC: constify snd_soc_codec_driver structures Check for snd_soc_codec_driver structures that are only passed to snd_soc_register_codec or memcpy (2nd arg), for which the corresponding parameters are declared const. Declare as const snd_soc_codec_driver structures that have these properties. 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_codec_driver i@p = { ... }; @ok@ identifier r.i; expression e1,e2,e3; position p; @@ ( snd_soc_register_codec(e1,&i@p,e2,e3) | memcpy(e1,&i@p,e2) ) @bad@ position p != {r.p,ok.p}; identifier r.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct snd_soc_codec_driver i = { ... }; // Signed-off-by: Julia Lawall Acked-by: Charles Keepax Signed-off-by: Mark Brown --- sound/soc/codecs/wm8770.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sound/soc/codecs/wm8770.c') diff --git a/sound/soc/codecs/wm8770.c b/sound/soc/codecs/wm8770.c index 8783a5fc123e..d6edcbbdec12 100644 --- a/sound/soc/codecs/wm8770.c +++ b/sound/soc/codecs/wm8770.c @@ -608,7 +608,7 @@ err_reg_enable: return ret; } -static struct snd_soc_codec_driver soc_codec_dev_wm8770 = { +static const struct snd_soc_codec_driver soc_codec_dev_wm8770 = { .probe = wm8770_probe, .set_bias_level = wm8770_set_bias_level, .idle_bias_off = true, -- cgit v1.2.3
