Subject: [PATCH][next] xen/gntdev: remove redundant non-zero check on ret
Date: Mon, 11 Nov 2019 12:20:09 +0000 [thread overview]
Message-ID: <20191111122009.67789-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The non-zero check on ret is always going to be false because
ret was initialized as zero and the only place it is set to
non-zero contains a return path before the non-zero check. Hence
the check is redundant and can be removed.
Addresses-Coverity: ("Logically dead code")
