Hi Takashi,

https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit/?h=for-next&id=98081ca62cbac31fb0f7efaf90b2e7384ce22257

Use upper patch to print power state in function alc256_init() and alc256_shutup().
But when kernel turn on power_save = 1. (echo 1 > /sys/module/snd_hda_intel/parameters/power_save)

The print power state value always be 0x0. ( If it turn off power save, power state value will normally)

BR,
Kailang
