This was an older version of the patch (sorry for the confusion),
please apply this fix patch on top of net-next.

I've diffed the relevant files in my branch head against net-next
plus this patch, and that looks as intended.

Thanks for your time!

    phylib: two dynamic mii_bus allocation fallout fixes
    
    1. arch/powerpc/platforms/pasemi/gpio_mdio.c also needs to be
       converted over to mdiobus_{alloc,free}().
    
    2. drivers/net/phy/fixed.c used to embed a struct mii_bus into its
       struct fixed_mdio_bus and then use container_of() to go from the
       former to the latter.  Since mii bus structures are no longer
       embedded, we need to do something like use the mii bus private
       pointer to go from mii_bus to fixed_mdio_bus instead.

Applied, thanks for catching this Lennert.
