Sherry Sun b202400c9c tty: serial: lpuart: disable flow control while waiting for the transmit engine to complete ... commit d5a2e08343 upstream. When the user initializes the uart port, and waits for the transmit engine to complete in lpuart32_set_termios(), if the UART TX fifo has dirty data and the UARTMODIR enable the flow control, the TX fifo may never be empty. So here we should disable the flow control first to make sure the transmit engin can complete.
