Subject: [PATCH 15/27] scsi: merge print_opcode_name()
Date: Mon, 20 Oct 2014 08:52:18 +0200 [thread overview]
Message-ID: <1413787950-14659-16-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1413787950-14659-1-git-send-email-hare@suse.de>
Instead of having two versions of print_opcode_name() we
should be consolidating them into one version.
