Subject: [alsa-devel] [PATCH 32/58] ALSA: aoa: Constify snd_kcontrol_new items
Date: Fri,  3 Jan 2020 09:16:48 +0100
Message-ID: <20200103081714.9560-33-tiwai@suse.de> (raw)
In-Reply-To: <20200103081714.9560-1-tiwai@suse.de>

Most of snd_kcontrol_new definitions are read-only and passed as-is.
Let's declare them as const for further optimization.

There should be no functional changes by this patch.
