Ah! Not good.
fixed_phy_add() is the lower layer call. What we can do is only access
fmb->mii_bus->irq[phy_addr] if irq != PHY_POLL. That should make ar7
and bcm47xx work again.
The higher level function fixed_phy_register() should return
-EPROBE_DEFER if fixed_mdio_bus_init() has not been called yet.
Thanks
