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 files is shown by the following output of the size command, first before then after the transformation:
