I don't think it's the right way of fixing the problem. If there is no
dependency on the two devices through the device model (i.e they don't
have a parent->child relationship), then the mv643xx_eth driver should
probably return -EPROBE_DEFER when it can't find its PHY so that its
->probe() operation gets called once again by the kernel when other
drivers (including mvmdio) have been probed.
Best regards,
Thomas
