To clarify to everyone possibly affected by this bug, and in reviewing the thread @Henrik provided, it seems like the upstream community (linux-uvc) has reviewed the patch and asked for some modifications (April 27, 2016). So that is why the patch has not made its way into Ubuntu kernels yet, as it's not yet fixed upstream.
@Henrik, do you have any update on that side of things?
