Subject: [PATCH 09/19] drbd: Deletion of an unnecessary check before the function call "lc_destroy"
Date: Thu, 30 Jul 2015 13:21:44 +0200 [thread overview]
Message-ID: <1438255314-14877-10-git-send-email-philipp.reisner@linbit.com> (raw)
In-Reply-To: <1438255314-14877-1-git-send-email-philipp.reisner@linbit.com>
From: Markus Elfring <elfring@users.sourceforge.net>
The lc_destroy() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
