ALSA: hda - Force polling mode on CNL for fixing codec communication
We observed the same issue as reported by commit a8d7bde23e7130686b7662 ("ALSA: hda - Force polling mode on CFL for fixing codec communication") We don't have a better solution. So apply the same workaround to CNL. Signed-off-by: Bard Liao <yung-chuan.liao@linux.intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
