ASoC: codecs: add const to snd_soc_codec_driver structures
Declare snd_soc_codec_driver structures as const as they are only passed as an argument to the function snd_soc_register_codec. This argument is of type const, so declare the structures with this property as const. In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in a copy operation along with getting passed to snd_soc_register_codec. So, it can be made const too. Done using Coccinelle: @match disable optional_qualifier@ identifier s; position p; @@ static struct snd_soc_codec_driver s@p={...}; @good1@ identifier match.s; position p; @@ snd_soc_register_codec(...,&s@p,...) @bad@ identifier match.s; position p!={match.p,good1.p}; @@ s@p @depends on !bad disable optional_qualifier@ identifier match.s; @@ static +const struct snd_soc_codec_driver s={...}; Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
