Revision 38faddb1afdd37218c196ac3db1cb5fbe7fc9c75 authored by Takashi Iwai on 28 July 2010, 12:21:55 UTC, committed by Takashi Iwai on 28 July 2010, 12:26:14 UTC
The behavior of Nvidia HDMI codec regarding the pin-detection unsol events
is based on the old HD-audio spec, i.e. PD bit indicates only the update
and doesn't show the current state.  Since the current code assumes the
new behavior, the pin-detection doesn't work relialby with these h/w.

This patch adds a flag for indicating the old spec, and fixes the issue
by checking the pin-detection explicitly for such hardware.
