Why is this patch necessary?

Sorry, I didn't notice the check in virtio_dev_probe(),

As Jason comment,  I alsoe think we need to be consistent: switch to use virtio_device_ready() for all the drivers. What's opinion about this?

The core virtio_dev_probe() code already calls virtio_device_ready for
us:

static int virtio_dev_probe(struct device *_d)
{
...
err = drv->probe(dev);
if (err)
goto err;
/* If probe didn't do it, mark device DRIVER_OK ourselves. */
if (!(dev->config->get_status(dev) & VIRTIO_CONFIG_S_DRIVER_OK))
virtio_device_ready(dev);
