ALSA: sound/isa: constify snd_kcontrol_new structures
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;
