Is there any reason why we can't use connector->real_edid_checksum all the time?
real_edid_checksum only calculated by drm when edid checksum vitrification failed after edid read. In the good edid checksum case (edid verification succeed), real_edid_checksum is not calculated by drm.
dp_link_send_edid_checksum(panel->link, checksum); dp_link_send_test_response(panel->link);
