tty: serial: lpuart: avoid leaking struct tty_structColibri-VF_LXDE-Image_2.8b4.129-20181005
The function tty_port_tty_get() gets a reference to the tty. Since the code is not using tty_port_tty_set(), the reference is kept even after closing the tty. Avoid using tty_port_tty_get() by directly access the tty instance. Since lpuart_start_rx_dma() is called from the .startup() and .set_termios() callback, it is safe to assume the tty instance is valid.
