The code boils down to: static const u8 in[7], out[5]; then, when the argument is UART_SCR, read in[7] or out[7] to determine where to __raw_readl() or __raw_writel(). Are you saying there's no point in fixing that, because there is no visible brokenness? Can you confirm that your test runs hit serial8250_suspend_port? (I will sprinkle the code with printk, if I ever I get my port working.)
