IMO, this would look a lot nicer if you make a function out of it (but
perhaps it can be changed in a follow-up patch):
#ifdef CONFIG_ACPI_SPCR_TABLE
static void qpdf2400_erratum44_workaround(struct platform_device *pdev,
struct uart_amba_port *uap)
{
if (!qdf2400_e44_present)
return;
dev_info(&pdev->dev, "working around QDF2400 SoC erratum 44\n");
uap->vendor = &vendor_qdt_qdf2400_e44;
}
#else
static void qpdf2400_erratum44_workaround(struct platform_device *pdev,
struct uart_amba_port *uap) { }
#endif
static int sbsa_uart_probe(struct platform_device *pdev)
{
...
uap->vendor = &vendor_sbsa;
qpdf2400_erratum44_workaround(pdev, uap);
...
}
