syz-executor.1/30135 is trying to acquire lock:

 (console_owner){-...}, at: [<ffffffff8145a92a>] vprintk_emit+0x32a/0x620 kernel/printk/printk.c:1922

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:

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);
