To fix the RX cancel command failure, rx_fifo buffer needs to be flushed in stop_rx() by calling handle_rx().In handle_rx() the data in rx_fifo buffer is read and then dropped, not sent to upper layers. If set_termios is called before startup, by this time memory is not allocated to port->rx_fifo buffer, which leads to a NULL pointer dereference. To avoid this NULL pointer dereference allocate memory to port->rx_fifo in probe itself.
