[alsa-devel] [PATCH 1/1] ALSA: hda - bug fix for invalid connection list of more Haswell HDMI codec pins

[mengdong.lin at intel.com]

From: Mengdong Lin <mengdong.lin at intel.com>

Haswell HDMI codec may report invalid connection list entries on all three
pins. But our previous patch only fixes the HDMI pin, not the DP pin, so
audio playbak via DP can still fail.

This patch adds fixup for Haswell to set proper connection list entries for
the other 2 pins including the DP pin.
