syz-executor/12829 is trying to acquire lock:
ffff88803079c598 (&p->pi_lock){-.-.}-{2:2}, at: try_to_wake_up+0x5c/0x1080 kernel/sched/core.c:4112

but task is already holding lock:
ffff888058641528 (&tty->write_wait){-...}-{2:2}, at: __wake_up_common_lock kernel/sched/wait.c:137 [inline]
ffff888058641528 (&tty->write_wait){-...}-{2:2}, at: __wake_up+0xf4/0x190 kernel/sched/wait.c:160

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:
  &p->pi_lock --> &port_lock_key --> &tty->write_wait

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&tty->write_wait);
                               lock(&port_lock_key);
                               lock(&tty->write_wait);
  lock(&p->pi_lock);
