From 71b1e9e43d5199f57c109e20c0f4dffc5c048130 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 13 Feb 2012 11:55:02 +0100 Subject: ALSA: hda - Add codec->no_jack_detect flag 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.
