Subject: [PATCH 5/9] ALSA: firewire-motu: code refactoring for packet format detection in v2 protocol
Date: Wed, 23 Jun 2021 16:59:37 +0900 [thread overview]
Message-ID: <20210623075941.72562-6-o-takashi@sakamocchi.jp> (raw)
In-Reply-To: <20210623075941.72562-1-o-takashi@sakamocchi.jp>
Current implementation of driver has several similar helper functions
for packet format detection in protocol version 2.
This commit merges them as code refactoring.
