From 3a84d6c940e666d85b1c58bbcda2248c54faa898 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Wed, 17 May 2017 17:08:56 +0530 Subject: 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.
