The pause flag doesn't appear to serve a purpose as it is possible for the pump worker thread to not be running when new buffers are queued. Before the following change was introduced: "43cd0023872e usb: gadget: uvc_video: add worker to handle the frame pumping", the pause flag status was discarded and never returned. This masked a current issues of the userspace receiving non-zero values (considered unsuccessful) and prevents trace_v4l2_qbuf() from being called.
