From 5164d6aac0ed1b711a7b29bb556844e40f422ec6 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 3 Feb 2015 11:27:38 -0300 Subject: [PATCH] [media] V4L2: Delete an unnecessary check before the function call "media_entity_put" 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.
