For dyn_pcm_assign: Driver will not use hda_jack. It will operate snd_jack directly. snd_jack pointer will be stored in spec->pcm.jack. When pcm is assigned to pin, jack will be assigned to pin automatically. For !dyn_pcm_assign: Driver will continue using hda_jack for less impact on the old cases. Pcm is statically assigned to pin. So is jack. spec->pcm.jack will save the snd_jack pointer created in hda_jack.
