The patch makes this callback optional and removes dumb implementations. v2: Rebase: - imx move to a shared (but still dummy) ->mode_valid implementation. - probe helpers have been extracted to drm_probe_helper.c Signed-off-by: Andrzej Hajda (v1) Signed-off-by: Daniel Vetter --- drivers/gpu/drm/drm_probe_helper.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/gpu/drm/drm_probe_helper.c') diff --git a/drivers/gpu/drm/drm_probe_helper.c b/drivers/gpu/drm/drm_probe_helper.c index e70f54d4a581..d06340985a72 100644 --- a/drivers/gpu/drm/drm_probe_helper.c +++ b/drivers/gpu/drm/drm_probe_helper.c @@ -169,7 +169,7 @@ int drm_helper_probe_single_connector_modes(struct drm_connector *connector, drm_mode_validate_flag(connector, mode_flags); list_for_each_entry(mode, &connector->modes, head) { - if (mode->status == MODE_OK) + if (mode->status == MODE_OK && connector_funcs->mode_valid) mode->status = connector_funcs->mode_valid(connector, mode); } -- cgit v1.2.3
