The driver can match only via the DT table (all platforms are OF-only) 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-s3c64xx.c:1496:34: error: ‘s3c64xx_spi_dt_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- drivers/spi/spi-s3c64xx.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/spi/spi-s3c64xx.c b/drivers/spi/spi-s3c64xx.c index cc69f8ffdbdc..7aec496070e2 100644 --- a/drivers/spi/spi-s3c64xx.c +++ b/drivers/spi/spi-s3c64xx.c @@ -1526,7 +1526,7 @@ static struct platform_driver s3c64xx_spi_driver = { .driver = { .name = "s3c64xx-spi", .pm = &s3c64xx_spi_pm, - .of_match_table = of_match_ptr(s3c64xx_spi_dt_match), + .of_match_table = s3c64xx_spi_dt_match, }, .probe = s3c64xx_spi_probe, .remove_new = s3c64xx_spi_remove, -- 2.34.1
