Hi,

- From patch 1:

> +    hr = init_device(object, 1, iface, ddraw, render_target, width, height);
> +    if (FAILED(hr))
> +        d3drm_device_destroy(object);
> +    else
> +        *device = IDirect3DRMDevice_from_impl(object);
Aren't you leaking ddraw here? It's possible that d3drm_device_destroy destroys it because ddraw is stored in object, but the caller doesn't know this. I'd be better to explicitly destroy it.

What about render_target in this case? Clipper isn't a problem because you didn't create it - the application did.

> +    if (FAILED(hr))
> +        return hr;
Here you have to release clipper (because you addref'ed it) and the primary surface.

You can avoid the clipper release by addrefing it after the CreateSurface call. AddRef never fails.
