From 8fdaebbb83b4e734c7ec1fcab5f1b26ec264965d Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Wed, 12 Apr 2017 18:38:06 +0530 Subject: ALSA: usb-audio: constify snd_kcontrol_new structures Declare snd_kcontrol_new strcutures as const as they are only passed as 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 too.
