Subject: [PATCH 20/27] sd: Cleanup logging
Date: Mon, 20 Oct 2014 08:52:23 +0200	[thread overview]
Message-ID: <1413787950-14659-21-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1413787950-14659-1-git-send-email-hare@suse.de>

Open-code scsi_print_result in sd.c, and cleanup logging to
not print duplicate informations.

With that we can remove scsi_show_result in constants.c
