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/ieee802154/ca8210.c:3174:34: error: ‘ca8210_of_ids’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- drivers/net/ieee802154/ca8210.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/ieee802154/ca8210.c b/drivers/net/ieee802154/ca8210.c index ed6cb79072a8..65d28e8a87c9 100644 --- a/drivers/net/ieee802154/ca8210.c +++ b/drivers/net/ieee802154/ca8210.c @@ -3181,7 +3181,7 @@ static struct spi_driver ca8210_spi_driver = { .driver = { .name = DRIVER_NAME, .owner = THIS_MODULE, - .of_match_table = of_match_ptr(ca8210_of_ids), + .of_match_table = ca8210_of_ids, }, .probe = ca8210_probe, .remove = ca8210_remove -- 2.34.1
