Subject: [PATCH 11/14] ALSA: firewire-motu: remove obsoleted codes
Date: Tue, 19 May 2020 20:16:38 +0900	[thread overview]
Message-ID: <20200519111641.123211-12-o-takashi@sakamocchi.jp> (raw)
In-Reply-To: <20200519111641.123211-1-o-takashi@sakamocchi.jp>

The way to decide CIP payload size by calculation with any flag is now
obsoleted. This commit removes the codes.
