The smsc911c driver puts its device into low power state when entering system suspend. Although it doesn't update the device's runtime PM status to RPM_SUSPENDED, which causes problems for a parent device. In particular, when the runtime PM status of the parent is requested to be updated to RPM_SUSPENDED, the runtime PM core prevent this, because it's forbidden to runtime suspend a device, which has an active child. Fix this by updating the runtime PM status of the smsc911x device to RPM_SUSPENDED during system suspend. In system resume, let's reverse that action by runtime resuming the device and thus also the parent.
