Subject: [PATCH nf-next] net-ipvs: Delete an unnecessary check before the function call "module_put"
Date: Fri, 10 Jul 2015 15:42:49 +0900	[thread overview]
Message-ID: <1436510569-10752-2-git-send-email-horms@verge.net.au> (raw)
In-Reply-To: <1436510569-10752-1-git-send-email-horms@verge.net.au>

From: Markus Elfring <elfring@users.sourceforge.net>

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.
