Staging: most: aim-sound: constify snd_pcm_ops structures
Check for snd_pcm_ops structures that are only passed as the third
argument to the function snd_pcm_set_ops. As this argument is
constant, so snd_pcm_ops structures having this property can also be
made constant.
Done using coccinelle:
@r1 disable optional_qualifier @
identifier i;
position p;
@@
static struct snd_pcm_ops i@p = {...};
@ok1@
identifier r1.i;
position p;
expression e1,e2;

snd_pcm_set_ops(e1,e2,&i@p)
