[alsa-devel] Realtek model parser problem with the new jack detection

I'm troubleshooting a problem with the Realtek quirk/model parsers. The
problem is basically that add_jack_kctls call
snd_hda_jack_detect_enable, which in turn overwrites the current unsol tag.
E g, first the model parser sets a pin to AC_USRSP_EN | ALC_HP_EVENT,
then comes snd_hda_jack_detect_enable and does AC_USRSP_EN | jack->tag.
I'm not sure of the best way to resolve this; either keep the current
tag (and mark all jacks as dirty on an unsol event), or read back the
current tag and set it as jack->action (and then always use the jack
table). What do you think?
