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 is not relevant here). drivers/spmi/spmi-mtk-pmif.c:517:34: error: ‘mtk_spmi_match_table’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- drivers/spmi/spmi-mtk-pmif.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/spmi/spmi-mtk-pmif.c b/drivers/spmi/spmi-mtk-pmif.c index ad511f2c3324..b8583917fa11 100644 --- a/drivers/spmi/spmi-mtk-pmif.c +++ b/drivers/spmi/spmi-mtk-pmif.c @@ -530,7 +530,7 @@ MODULE_DEVICE_TABLE(of, mtk_spmi_match_table); static struct platform_driver mtk_spmi_driver = { .driver = { .name = "spmi-mtk", - .of_match_table = of_match_ptr(mtk_spmi_match_table), + .of_match_table = mtk_spmi_match_table, }, .probe = mtk_spmi_probe, .remove = mtk_spmi_remove, -- 2.34.1
