2016-10-24ASoC: atmel_wm8904: constify snd_soc_ops structuresJulia Lawall1-1/+1
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/) // <smpl> @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 = { ... }; // </smpl> 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 2611 1536 0 4147 1033 sound/soc/atmel/atmel_wm8904.o 2675 1480 0 4155 103b sound/soc/atmel/atmel_wm8904.o Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
