Markus Elfring ae1b22658e ALSA: ice17xx: Deletion of unnecessary checks before the function call "snd_ac97_resume" 
The snd_ac97_resume() 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.
