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/bluetooth/hci_ll.c:769:34: error: ‘hci_ti_of_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- drivers/bluetooth/hci_ll.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/bluetooth/hci_ll.c b/drivers/bluetooth/hci_ll.c index 5abc01a2acf7..4a0b5c3160c2 100644 --- a/drivers/bluetooth/hci_ll.c +++ b/drivers/bluetooth/hci_ll.c @@ -786,7 +786,7 @@ MODULE_DEVICE_TABLE(of, hci_ti_of_match); static struct serdev_device_driver hci_ti_drv = { .driver = { .name = "hci-ti", - .of_match_table = of_match_ptr(hci_ti_of_match), + .of_match_table = hci_ti_of_match, }, .probe = hci_ti_probe, .remove = hci_ti_remove, -- 2.34.1
