Subject: [PATCH] scsi: fc: remove redundant check of an unsigned long being less than zero
Date: Fri, 14 Apr 2017 13:58:02 +0000 [thread overview]
Message-ID: <20170414135802.6991-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The check for an unsigned long being less than zero is always false
so it is a redundant check and can be removed.
