What was the reason for this part?
As written it is going to cause problems, the driver will forget about
earlier errors if the endpoint is stopped and resumed on the same TD.
I think that the whole patch could be much simpler, like:
case X_ERROR:
frame->status = X;
td->error_mid_td = true;
break;
case Y_ERROR:
frame->status = Y;
td->error_mid_td = true;
break;
and then
if (error_mid_td && (ep_trb != td->end_trb || ETRON && SUPERSPEED)) {
// error mid TD, wait for final event
}
finish_td()
