Subject: [PATCH 9/13] ALSA: i2sbus: Delete an unnecessary check before the function call "snd_pcm_suspend_all"
Date: Sun, 04 Jan 2015 14:21:43 +0100 [thread overview]
Message-ID: <54A93E67.8070105@users.sourceforge.net> (raw)
In-Reply-To: <54A9355F.4050102@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 3 Jan 2015 20:43:01 +0100
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.
