syz-executor.2/31270 is trying to acquire lock:

which lock already depends on the new lock.

other info that might help us debug this:

Chain exists of:
  console_owner --> &port_lock_key --> &(&port->lock)->rlock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&(&port->lock)->rlock);

                               lock(&(&port->lock)->rlock);
