Sherry Sun 6942fbc009 tty: serial: fsl_lpuart: fix the potential risk of division or modulo by zero ... [ Upstream commit fcb10ee27f ] We should be very careful about the register values that will be used for division or modulo operations, althrough the possibility that the UARTBAUD register value is zero is very low, but we had better to deal with the "bad data" of hardware in advance to avoid division or modulo by zero leading to undefined kernel behavior.
