That callback is used by some transports\n(e.g. virtio-pci) to enable interrupts.\n\nLet's fix it, by calling virtio_device_ready() as we do in\nvirtio_dev_probe(). This function calls .enable_cts callback and sets\nDRIVER_OK status bit.\n\nThis fix also avoids setting DRIVER_OK twice for those drivers that\ncall virtio_device_ready() in the .restore."
