[PATCH] [media] V4L2: Delete an unnecessary check before the function call "media_entity_put"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 3 Feb 2015 15:27:38 +0100

The media_entity_put() 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.
