[PATCH 1/1] USB: gadget: function: Deletion of an unnecessary check before the function call "rndis_add_hdr"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 21 Nov 2014 14:51:43 +0100

The rndis_add_hdr() 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.
