Subject: [PATCH] tools lib traceevent: Delete an unnecessary check before
the function call "free_arg"
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 25 Jun 2015 16:13:47 +0200
The free_arg() 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.
