From f68b3b291d39f1e3361b194a95459f9cbdaf31e6 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 17 Sep 2010 14:45:14 +0200 Subject: ALSA: hda - Check the external mic pin more strictly for Conexant chips The external mic jack for auto-mic switch must be really an external jack and with a presense-detection capability. This patch makes the check more paranoia.
