The device_driver structure's of_match_table field exists unconditionally, so there's no need for of_match_ptr(). This fixes a compiler warning when test-compiling on non-OF platforms: drivers/media/platform/renesas/rcar_drif.c:1470:34: warning: unused variable 'rcar_drif_of_table' [-Wunused-const-variable] static const struct of_device_id rcar_drif_of_table[] = { ^ Reported-by: kernel test robot <lkp@xxxxxxxxx> Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@xxxxxxxxxxxxxxxx> --- drivers/media/platform/renesas/rcar_drif.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/media/platform/renesas/rcar_drif.c b/drivers/media/platform/renesas/rcar_drif.c index 9a0982fa5c6b..5167960781bf 100644 --- a/drivers/media/platform/renesas/rcar_drif.c +++ b/drivers/media/platform/renesas/rcar_drif.c @@ -1477,7 +1477,7 @@ MODULE_DEVICE_TABLE(of, rcar_drif_of_table); static struct platform_driver rcar_drif_driver = { .driver = { .name = RCAR_DRIF_DRV_NAME, - .of_match_table = of_match_ptr(rcar_drif_of_table), + .of_match_table = rcar_drif_of_table, .pm = &rcar_drif_pm_ops, }, .probe = rcar_drif_probe, base-commit: 6c1c1eb8c87de221051b9198d40971640060842f -- Regards, Laurent Pinchart
