serial: access after NULL check in uart_flush_buffer()
I noticed that static void uart_flush_buffer(struct tty_struct *tty) { struct uart_state *state = tty->driver_data; struct uart_port *port = state->port; unsigned long flags; /* * This means you called this function _after_ the port was * closed. No cookie for you. */ if (!state || !state->info) { WARN_ON(1); return; } is too late for checking state != NULL.
