The jack detection side of this looks good - I've not really reviewed
the HDA side of things.  One comment:

So SND_JACK_SWITCH is just a jack that can be either headphone or
lineout - like I said previously, you should not define a new jack type
for this but just set both jack types when registering the jack.
