Guennadi Liakhovetski e5225c820c media: uvcvideo: Send a control event when a Control Change interrupt arrives
UVC defines a method of handling asynchronous controls, which sends a
USB packet over the interrupt pipe. This patch implements support for
such packets by sending a control event to the user. Since this can
involve USB traffic and, therefore, scheduling, this has to be done
in a work queue.
