From 5c34fdf48b9522ca87372b1fae19de8f93ffd130 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 2 Dec 2014 18:52:21 +0100 Subject: [PATCH] ALSA: trident: Deletion of a check before snd_util_memhdr_free() The snd_util_memhdr_free() 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.
