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/net/dsa/ocelot/seville_vsc9953.c:1070:34: error: ‘seville_of_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- drivers/net/dsa/ocelot/seville_vsc9953.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/dsa/ocelot/seville_vsc9953.c b/drivers/net/dsa/ocelot/seville_vsc9953.c index 563ad338da25..96d4972a62f0 100644 --- a/drivers/net/dsa/ocelot/seville_vsc9953.c +++ b/drivers/net/dsa/ocelot/seville_vsc9953.c @@ -1079,7 +1079,7 @@ static struct platform_driver seville_vsc9953_driver = { .shutdown = seville_shutdown, .driver = { .name = "mscc_seville", - .of_match_table = of_match_ptr(seville_of_match), + .of_match_table = seville_of_match, }, }; module_platform_driver(seville_vsc9953_driver); -- 2.34.1
