Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi.

This driver calls drm_detect_hdmi_monitor() to receive the same
information, which is less efficient.

Avoid calling drm_detect_hdmi_monitor() and use drm_display_info.is_hdmi
instead.

Sorry, but this is broken. The commit message contains the clue: "Once
EDID is parsed". drm_get_edid() does not parse the EDID, you need to
call drm_connector_update_edid_property() first.

This is what I posted some time ago [1] but apparently was working on a
different baseline.

BR,
Jani.
