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/media/cec/platform/meson/ao-cec.c:711:34: error: ‘meson_ao_cec_of_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- drivers/media/cec/platform/meson/ao-cec.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/media/cec/platform/meson/ao-cec.c b/drivers/media/cec/platform/meson/ao-cec.c index 6b440f0635d9..223c092dbb6a 100644 --- a/drivers/media/cec/platform/meson/ao-cec.c +++ b/drivers/media/cec/platform/meson/ao-cec.c @@ -719,7 +719,7 @@ static struct platform_driver meson_ao_cec_driver = { .remove = meson_ao_cec_remove, .driver = { .name = "meson-ao-cec", - .of_match_table = of_match_ptr(meson_ao_cec_of_match), + .of_match_table = meson_ao_cec_of_match, }, }; -- 2.34.1
