[PATCH] ALSA: declare snd_kcontrol_new structures as const
Bhumika Goyal

Sun May 28 00:46:15 AEST 2017
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:

identifier x;

static struct snd_kcontrol_new x at p={...};
