Subject: [PATCH] fjes: Delete an unnecessary check before the function call
 "vfree"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 6 Nov 2015 09:30:29 +0100

The vfree() function performs also input parameter validation.
Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
