From aa57b93b27eae1156c9a66a4ea85076f9a38d135 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sat, 3 Jan 2015 20:43:01 +0100 Subject: [PATCH] ALSA: aoa: Delete an unnecessary check before the function call "snd_pcm_suspend_all" The snd_pcm_suspend_all() 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.
