Krzysztof Opasiak 91c42b0da8 usb: gadget: loopback: Fix looping back logic implementation ... Since commit e0857ce58e ("usb: gadget: loopback: don't queue requests to bogus endpoints") Loopback function is not realy working as that commit removed all looping back logic. After that commit ep-out works like /dev/null and ep-in works like /dev/zero. This commit fix this issue by allocating set of out requests and set of in requests but each out req shares buffer with one in req: out_req->buf ---> buf <--- in_req.buf out_req->context <---> in_req.context The completion routine simply enqueue the suitable req in an oposite direction.
