ALSA: constify snd_pcm_ops structures
Check for snd_pcm_ops structures that are only stored in the ops field of a snd_soc_platform_driver structure or passed as the third argument to snd_pcm_set_ops. The corresponding field or parameter is declared const, so snd_pcm_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_pcm_ops i@p = { ... }; @ok1@ identifier r.i; struct snd_soc_platform_driver e; position p; @@ e.ops = &i@p; @ok2@ identifier r.i; expression e1, e2; position p; @@ snd_pcm_set_ops(e1, e2, &i@p) @bad@ position p != {r.p,ok1.p,ok2.p}; identifier r.i; struct snd_pcm_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct snd_pcm_ops i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Takashi Iwai <tiwai@suse.de>
