Subject: [alsa-devel] [PATCH 10/68] ALSA: ac97: More constifications
Date: Sun,  5 Jan 2020 15:47:25 +0100
Message-ID: <20200105144823.29547-11-tiwai@suse.de> (raw)
In-Reply-To: <20200105144823.29547-1-tiwai@suse.de>

Apply const prefix to each possible place: the static tables for
registers and bits, the quirk tables, etc.

Just for minor optimization and no functional changes.

Signed-off-by: Takashi Iwai <tiwai@suse.de>
