Subject: [PATCH 29/40] aha152x: modify done() to use separate status bytes
Date: Tue, 27 Apr 2021 10:30:35 +0200 [thread overview]
Message-ID: <20210427083046.31620-30-hare@suse.de> (raw)
In-Reply-To: <20210427083046.31620-1-hare@suse.de>
Instead of passing in the combined SCSI result value split them
off into separate status, message, and host byte values.
Signed-off-by: Hannes Reinecke <hare@suse.de>
