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. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
