ALSA: hda - Yet another fix for broken HSW HDMI pin connections
A Haswell test machine showed that the invalid connection list, but this time it has only a single pin on the codec, thus the former fixup code doesn't work as it assumes the three pins blindly. This patch splits the former fixup code to two parts: - Enable eDP 1.2 for Haswell codec - Fix the connection list of pins on Haswell codec; the converter list is recorded dynamically in hdmi_add_cvt(), and applied in hdmi_add_pin() Signed-off-by: Mengdong Lin <mengdong.lin@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
