The driver will match mostly by DT table (even thought there is regular ID table) so there is little benefit in of_match_ptr (this also allows ACPI matching via PRP0001, even though it might not be relevant here). drivers/net/ieee802154/adf7242.c:1322:34: error: ‘adf7242_of_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- drivers/net/ieee802154/adf7242.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/ieee802154/adf7242.c b/drivers/net/ieee802154/adf7242.c index 5cf218c674a5..509acc86001c 100644 --- a/drivers/net/ieee802154/adf7242.c +++ b/drivers/net/ieee802154/adf7242.c @@ -1336,7 +1336,7 @@ MODULE_DEVICE_TABLE(spi, adf7242_device_id); static struct spi_driver adf7242_driver = { .id_table = adf7242_device_id, .driver = { - .of_match_table = of_match_ptr(adf7242_of_match), + .of_match_table = adf7242_of_match, .name = "adf7242", .owner = THIS_MODULE, }, -- 2.34.1
