Subject[ 40/69] ALSA: hda - Add codec->no_jack_detect flag
3.2-stable review patch.  If anyone has any objections, please let me know.

------------------
From: Takashi Iwai <tiwai@suse.de>

commit 71b1e9e43d5199f57c109e20c0f4dffc5c048130 upstream.

Add a new flag to indicate that the codec has no jack-detection cap.
This flag should be set for hardwares that have no jack-detect
implementation although the codec chip itself supports it.
