[ALSA] hda-codec - Fix STAC922x volume knob control
Reported by zhejiang <zhe.jiang@intel.com> 'I found that STAC_VOLKNOB hardwired the KNOB nid to 0x24. It is okay for stac9205 and stac927x. But the VolumeKnob nid of stac9220-9221 is 0x16.' Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
