[alsa-devel] [PATCH 4/13] ALSA: oxygen: Delete an unnecessary check before the function call "snd_pcm_suspend"

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Sat, 3 Jan 2015 17:37:28 +0100

The snd_pcm_suspend() 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.
