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

From: SF Markus Elfring <hidden>
Date: 2015-01-04 13:00:33
Also in: alsa-devel, lkml
Subsystem: c-media cmi8788 driver, sound, the rest · Maintainers: Clemens Ladisch, Jaroslav Kysela, Takashi Iwai, Linus Torvalds

From: Markus Elfring <redacted>

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.
