ALSA: pci: constify snd_kcontrol_new structures
Declare snd_kcontrol_new structures as const as they are only passed as an argument to the function snd_ctl_new1. This argument is of type const, so snd_kcontrol_new structures having the same property can be made const too. Done using Coccinelle: @r1 disable optional_qualifier @ identifier i; position p; @@ static struct snd_kcontrol_new i@p = {...}; @ok1@ identifier r1.i; position p; expression e1; @@ snd_ctl_new1(&i@p,e1) @bad@ position p!={r1.p,ok1.p}; identifier r1.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r1.i; @@ +const struct snd_kcontrol_new i; Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
