[PATCH 5/6 v5] uvcvideo: send a control event when a Control Change interrupt arrives

2017-07-28 Thread Guennadi Liakhovetski
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.
