It's commit a71e3c37960ce5f9c6a519bc1215e3ba9fa83e75:

    net: phy: Set the driver when registering an MDIO bus device
    
    mdiobus_register() registers a device which is already bound to a driver.
    Hence, the driver pointer should be set properly in order to track down
    the driver associated to the MDIO bus.
    
    This will be used to allow ethernet driver to pin down a MDIO bus driver,
    preventing it from being unloaded while the PHY device is running.

What's bad is that this went in late during v3.16-rc fixes.  So now v3.16 
itself is broken, and there's no way to fix it.

As far as I can tell, this patch doesn't fix a regression.  So no way it 
should have gone in during late -rc kernels.
