Subject: [PATCH] net-ipvs: Delete an unnecessary check before the function call "module_put"
Date: Thu, 02 Jul 2015 17:10:41 +0200 [thread overview]
Message-ID: <55955471.9000501@users.sourceforge.net> (raw)
In-Reply-To: <20141119134040.GA12270@salvia>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Thu, 2 Jul 2015 17:00:14 +0200
The module_put() 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.
