Isn't it strange that dc_link_detect goes on when
edid_status==EDID_BAD_CHECKSUM but does return when
edid_status==EDID_NO_RESPONSE? In both cases, one cannot expect to have read a
valid EDID from the display at hand, but if it's ok to continue with an invalid
EDID, why not also continue without one having been received?
