-Subject: [PATCH 203/232] serial: Take care starting a hung-up tty's port
-
-tty_port_hangup sets a port's tty field to NULL (holding the port lock),
-but uart_tx_stopped, called from __uart_start (with the port lock),
-uses the tty field without checking for NULL.
-
-Change uart_tx_stopped to treat a NULL tty field as another stopped
-indication.
