3.6-stable review patch. If anyone has any objections, please let me know.
------------------ From: Herton Ronaldo Krzesinski <[email protected]> commit cf55e904516947597d75fd3844acc24891a95772 upstream. If headphone jack can't detect plug presence, and we have the jack in the jack table, snd_hda_jack_detect will return the plug as always present (as it'll be considered as a phantom jack). The problem is that when this happens, line out pins will always be disabled, resulting in no sound if there are no headphones connected. This was reported as a no sound problem after suspend on http://bugs.launchpad.net/bugs/1052499, since the bug doesn't manifests on first initialization before the phantom jack is added, but on resume we reexecute the initialization code, and via_hp_automute starts reporting HP always present with the jack now on the table.
