Hello, I explored gadget zero as an example, my focus is on struct usb_request and its buffer. I saw it is allocated in the set_config function (inside set_alt), and the "kfree(req->buf)" and "usb_ep_free_request(ep, req)" is only called in the complete routine. I know when the device is disconnected these free routines will be invoked, but how about changing configuration? the set_config(...) routine in composite.c only disables the ep, but not free the requests and their buffers. So that's my question, is this a possible memory leak?
