Building with W=1 shows a warning about hns_mdio_acpi_match being unused when
CONFIG_ACPI is disabled:

drivers/net/ethernet/hisilicon/hns_mdio.c:631:36: error: unused variable 'hns_mdio_acpi_match' [-Werror,-Wunused-const-variable]

Thank you.


But I think it can be changed to:

+ #ifdef CONFIG_ACPI
static const struct acpi_device_id hns_mdio_acpi_match[] = {
	{ "HISI0141", 0 },
	{ },
};
MODULE_DEVICE_TABLE(acpi, hns_mdio_acpi_match);
+ #endif

static struct platform_driver hns_mdio_driver = {
	.probe = hns_mdio_probe,
	.remove = hns_mdio_remove,
	.driver = {
		   .name = MDIO_DRV_NAME,
		   .of_match_table = hns_mdio_match,
		   .acpi_match_table = ACPI_PTR(hns_mdio_acpi_match),
		   },
};
