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/i2c/busses/i2c-owl.c:510:34: error: ‘owl_i2c_of_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- drivers/i2c/busses/i2c-owl.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/i2c/busses/i2c-owl.c b/drivers/i2c/busses/i2c-owl.c index 98882fe4e965..99ddd8894964 100644 --- a/drivers/i2c/busses/i2c-owl.c +++ b/drivers/i2c/busses/i2c-owl.c @@ -519,7 +519,7 @@ static struct platform_driver owl_i2c_driver = { .probe = owl_i2c_probe, .driver = { .name = "owl-i2c", - .of_match_table = of_match_ptr(owl_i2c_of_match), + .of_match_table = owl_i2c_of_match, .probe_type = PROBE_PREFER_ASYNCHRONOUS, }, }; -- 2.34.1
