From 07d0e554b5d10522b4cd6448108c0ad16403fea6 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 3 Feb 2015 12:01:40 -0300 Subject: [PATCH] [media] DVB: Delete an unnecessary check before the function call "dvb_unregister_device" The dvb_unregister_device() 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.
