Okay, so when I see the EDID arrive, I should be doing:

                phys = parse_hdmi_addr(block->edid);
                cec->adap->phys_addr = phys;
                cec_enable(cec->adap, true);

IOW, you _are_ expecting adap->phys_addr to be written, but only while
the adapter is disabled?

Thanks.
