Subject: [PATCHv2 01/14] libata: do not attempt to retrieve sense code twice
Date: Tue, 12 Apr 2016 08:47:45 +0200	[thread overview]
Message-ID: <1460443678-57934-2-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1460443678-57934-1-git-send-email-hare@suse.de>

Do not call ata_request_sense() if the sense code is already
present.
