| |
From: Markus Elfring <elfring@users.sourceforge.net> Date: Tue, 2 Dec 2014 18:34:45 +0100
The release_and_free_resource() 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.
