When some hardware is faulty, the error code cannot be set, and it just stops working. In addition, interrupts are generally not enabled. Therefore, for such hardware, the framework needs to have a mechanism to transmit the status so that applications can sense the status.
So how about extend vchan_idle to vchan_status, include: idle, running, error-stop ?
