When an Atmel SoC is suspended with the backup mode, the USB bus will be powered down. As this is expected, do not return an error to the driver core when ehci_resume detects it.

Ok, I agree with that as the underlying function takes care about the controller, in any case (even for !B+S-R case). So we don't have any added value to propagate this information. Acked-by: Nicolas Ferre <nicolas.ferre@microchip.com>
