From 6ba1ad386c30487aaa18a56da71fa12591131dd6 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Wed, 17 May 2017 17:20:46 +0530 Subject: [PATCH] ALSA: ice1712: 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.
