Subject: Re: [PATCH 1/2] net: phy: Set the driver when registering an MDIO bus device

2014-07-22 17:16 GMT-07:00 Ezequiel Garcia <ezequiel.garcia@...e-electrons.com>:
> 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.
