From b76c0e95ab0f535e210df588b8ac42dd75b31c75 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sat, 3 Jan 2015 21:02:32 +0100 Subject: [PATCH] ALSA: sb: Delete an unnecessary check before the function call "snd_emux_free" The snd_emux_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.
