David, please could you test this. But it Looks O.K. to me. Reviewed-by: Andrew Lunn <andrew@lunn.ch> Andrew

Convert mdiobus_register_reset() from open-coded DT-only optional reset handling to reset_control_get_optional_exclusive(). This not only simplifies the code, but also adds support for lookup-based resets on non-DT systems.
