Declare snd_kcontrol_new structures as const as they are only passed an argument to the function snd_ctl_new1. This argument is of type const, so snd_kcontrol_new structures having this property can be made const. Done using Coccinelle:
@r disable optional_qualifier@ identifier x; position p; @@ static struct snd_kcontrol_new x@p={...};
@ok@ identifier r.x; position p; @@ snd_ctl_new1(&x@p,...)
@bad@ position p != {r.p,ok.p}; identifier r.x; @@ x@p
@depends on !bad disable optional_qualifier@ identifier r.x; @@ +const struct snd_kcontrol_new x;
