Hmm, I must have missed this. It's great that you try to implement kctl 
jacks for ASoC, but your actual implementation seems to regress HDA, 
unless I'm missing something.

In particular, the phantom jacks currently show up in the kctl jack 
layer only, not in the /dev/input layer, and I prefer to keep it that 
way in order not to pollute the /dev/input layer with phantom jacks.
But it looks like these will just disappear (?!) with your patch, but 
I'm not entirely sure. Could you elaborate?
