Subject: [PATCH] ALSA: nm256: constify snd_ac97_res_table
Date: Thu, 24 Aug 2017 11:55:28 +0530	[thread overview]
Message-ID: <7aada04a5e083b027a5b846c0429aa6385c0ae1e.1503555844.git.arvind.yadav.cs@gmail.com> (raw)

snd_ac97_res_table are not supposed to change at runtime. All functions
working with snd_ac97_res_table provided by <sound/ac97_codec.h> work with
const snd_ac97_res_table. So mark the non-const structs as const.
