commit 924f5ca2975b2993ee81a7ecc3c809943a70f334 upstream.
On ASUSTeK Z170M PLUS and Z170 PRO GAMING systems, the display codec
pins are not registered properly without the force-connect quirk. The
codec will report only one pin as having external connectivity, but i915
finds all three connectors on the system, so the two drivers are not
in sync.
Issue found with DRM igt-gpu-tools test kms_hdmi_inject@inject-audio.
