Pawel Laszczak f616c3bda4 usb: cdns3: Fix dequeue implementation. ... Dequeuing implementation in cdns3_gadget_ep_dequeue gets first request from deferred_req_list and changed TRB associated with it to LINK TRB. This approach is incorrect because deferred_req_list contains requests that have not been placed on hardware RING. In this case driver should just giveback this request to gadget driver. The patch implements new approach that first checks where dequeuing request is located and only when it's on Transfer Ring then changes TRB associated with it to LINK TRB. During processing completed transfers such LINK TRB will be ignored.
