    drm/i915: sync hdmi detection by hdmi identifier with 2D · 9dff6af8
    Ma Ling authored
    Currently we detect HDMI monitor by hardware detection, but if an HDMI-DVI
    adapter is used to connect a DVI monitor, hardware detection will incorrectly
    take monitor as HDMI. HDMI spec says any device containing IEEE registration
    identifier will be treated as HDMI device.  The patch intends to detect HDMI
    monitor by drm_detect_hdmi_monitor function which follows that rule.
