You should also set these fields:
-- parent: set to the parent device (same device as was used to register
- v4l2_device).
+- v4l2_dev: set to the v4l2_device parent device.
- name: set to something descriptive and unique.
- fops: set to the file_operations struct.
- ioctl_ops: if you use the v4l2_ioctl_ops to simplify ioctl maintenance

You can go from a video_device struct to the v4l2_device struct using:
-struct v4l2_device *v4l2_dev = dev_get_drvdata(vdev->parent);
-
+struct v4l2_device *v4l2_dev = vdev->v4l2_dev;
