ac97->dev is an object of 'struct device' type. It should be initialized via device_initialize() or device_register().
Fixes: 74426fbff66e ("ALSA: ac97: add an ac97 bus") Signed-off-by: Lihua Yao ylhuajnu@163.com
Looks good though a quick glance, but I'd like to get an ack from Robert. Robert? Also check two other patches and runtime PM.
thanks,
Takashi
