So I painfully (exchanged 'good' for 'bad' in the middle and had
to restart all over) bisected this down to

    ALSA: hda - Add generic pincfg initialization

    Added the generic pincfg cache and save/restore functions.
    Also introduced the pin-overriding via hwdep sysfs.

It doesn't revert cleanly from the latest kernel, so I could not double 
check it.

OBS: All tests were done with the headphone plugged in.
