The problem here is somewhat lack of testers. We have only one person
with a headset (with alias Yuv) and that person reports that it does not
work. However, the problem might be with that person's headset so I
probably don't want to completely disable it, just remove its jack
detection. Especially as this would go to stable too.

But ok, I can make three patches, one for headset mic model, one for
sony, and a third that adds the connection between them.

Hmm, but maybe middle will have same problem if we end up changing the
policy. Maybe random position will be better? Or put all stable first
and all non-stable last?
