Elson Roy Serrao 03285557de usb: dwc3: gadget: Reset num TRBs before giving back the request ... commit 00f8205ffc upstream. Consider a scenario where cable disconnect happens when there is an active usb reqest queued to the UDC. As part of the disconnect we would issue an end transfer with no interrupt-on-completion before giving back this request. Since we are giving back the request without skipping TRBs the num_trbs field of dwc3_request still holds the stale value previously used. Function drivers re-use same request for a given bind-unbind session and hence their dwc3_request context gets preserved across cable disconnect/connect. When such a request gets re-queued after cable connect, we would increase the num_trbs field on top of the previous stale value thus incorrectly representing the number of TRBs used. Fix this by resetting num_trbs field before giving back the request.
