Subject: [alsa-devel] [PATCH 22/68] ALSA: usx2y: More constifications
Date: Sun,  5 Jan 2020 15:47:37 +0100
Message-ID: <20200105144823.29547-23-tiwai@suse.de> (raw)
In-Reply-To: <20200105144823.29547-1-tiwai@suse.de>

Apply const prefix to each possible place: the string array and the
parameter tables and callers.

Just for minor optimization and no functional changes.
