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 is not relevant here). drivers/spi/spi-meson-spifc.c:434:34: error: ‘meson_spifc_dt_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- drivers/spi/spi-meson-spifc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/spi/spi-meson-spifc.c b/drivers/spi/spi-meson-spifc.c index 06626f406f68..af832fbbf258 100644 --- a/drivers/spi/spi-meson-spifc.c +++ b/drivers/spi/spi-meson-spifc.c @@ -443,7 +443,7 @@ static struct platform_driver meson_spifc_driver = { .remove_new = meson_spifc_remove, .driver = { .name = "meson-spifc", - .of_match_table = of_match_ptr(meson_spifc_dt_match), + .of_match_table = meson_spifc_dt_match, .pm = &meson_spifc_pm_ops, }, }; -- 2.34.1
