The IBM camera driver just does this:
static int video_nr = -1;
if (video_register_device(&uvd->vdev, VFL_TYPE_GRABBER,video_nr) == -1) {
err("%s: video_register_device failed", proc);
return -EPIPE;
}
if (uvd->debug > 1) {
info("%s: video_register_device() successful", proc);
}
if (uvd->dev == NULL) {
err("%s: uvd->dev == NULL", proc);
return -EINVAL;
}
info("%s on /dev/video%d: canvas=%s videosize=%s",
(uvd->handle != NULL) ? uvd->handle->drvName : "???",
uvd->vdev.minor, tmp2, tmp1);
So if the device registration is successful then I guess videodev.o should
handle open() and other callbacks into the registered driver. If it
doesn't then it is broken, I suppose.
