The root cause was the introduction of the caps field in ivtv-driver.h. While loading the ivtvfb module would update the video_device device_caps field with V4L2_CAP_VIDEO_OUTPUT_OVERLAY it would not update that caps field, and that's what the overlay ioctls would look at. It's a bad idea to keep information in two places, so drop the caps field and only use vdev.device_caps.
