Hi Thomas

Reviewed-by: Andrew Lunn <andrew@lunn.ch>

However, i wounder if it makes sense to add a label before the
existing device_del() at the end of the function, and convert this,
and the case above into a goto? That might scale better, avoiding the
same issue in the future?

Thanks

    Andrew
