Pali Rohár 9ad82f0412 serial: mvebu-uart: do not allow changing baudrate when uartclk is not available ... [ Upstream commit ecd6b010d8 ] Testing mvuart->clk for non-error is not enough as mvuart->clk may contain valid clk pointer but when clk_prepare_enable(mvuart->clk) failed then port->uartclk is zero. When mvuart->clk is not available then port->uartclk is zero too. Parent clock rate port->uartclk is needed to calculate UART clock divisor and without it is not possible to change baudrate. So fix test condition when it is possible to change baudrate.
