From: Ville Syrjälä <ville.syrj...@linux.intel.com>
drm_mode_connector_update_edid_property() will call
drm_add_display_info() if an invalid edid is passed in.
This differs from the behaviour of drm_add_edid_modes() which
doesn't try to populate the display info from an invalid edid.
Adjust drm_mode_connector_update_edid_property() to match that
behaviour.
Unfortunately we have to pass the edid as non-const to
drm_mode_connector_update_edid_property() because drm_edid_is_valid()
may need to modify it :( Would be nice to one day fix up the EDID code
to not do crazy things like that.
