The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might not be relevant here). drivers/usb/host/xhci-rcar.c:269:34: error: ‘usb_xhci_of_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- drivers/usb/host/xhci-rcar.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/usb/host/xhci-rcar.c b/drivers/usb/host/xhci-rcar.c index 7f18509a1d39..b12c2c19d107 100644 --- a/drivers/usb/host/xhci-rcar.c +++ b/drivers/usb/host/xhci-rcar.c @@ -312,7 +312,7 @@ static struct platform_driver usb_xhci_renesas_driver = { .driver = { .name = "xhci-renesas-hcd", .pm = &xhci_plat_pm_ops, - .of_match_table = of_match_ptr(usb_xhci_of_match), + .of_match_table = usb_xhci_of_match, }, }; module_platform_driver(usb_xhci_renesas_driver); -- 2.34.1
