When the request is completed, all controls are copied to the request object. However, when VIDIOC_G_EXT_CTRLS attempts to read control values from the request it will read the current value instead for any control reference that has a NULL ref->req pointer. But that's wrong: after completing the request *all* controls should have a non-NULL ref->req pointer since they are after all copied to the request. So set ref->req if it wasn't set already.
