From 905e46acd3272d04566fec49afbd7ad9e2ed9ae3 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Sat, 27 May 2017 20:16:15 +0530 Subject: ALSA: declare snd_kcontrol_new structures as const 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.
