Subject: [PATCH] kdbus: Delete an unnecessary check before the function call
"kdbus_domain_unref"
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 24 Jun 2015 14:30:17 +0200
The kdbus_domain_unref() 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.
