Checking whether the driver uses atomic modeset is a better check instead as the property values are tracked in the state structures. v2: Included header Cc: Daniel Vetter Reviewed-by: Daniel Vetter Signed-off-by: Dhinakaran Pandiyan Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1482396643-32456-2-git-send-email-dhinakaran.pandiyan@intel.com --- diff --git a/drivers/gpu/drm/drm_mode_object.c b/drivers/gpu/drm/drm_mode_object.c index 9f17085b1fdd..14543ff08c51 100644 --- a/drivers/gpu/drm/drm_mode_object.c +++ b/drivers/gpu/drm/drm_mode_object.c @@ -23,6 +23,7 @@ #include #include #include +#include #include "drm_crtc_internal.h" @@ -273,7 +274,7 @@ int drm_object_property_get_value(struct drm_mode_object *obj, * their value in obj->properties->values[].. mostly to avoid * having to deal w/ EDID and similar props in atomic paths: */ - if (drm_core_check_feature(property->dev, DRIVER_ATOMIC) && + if (drm_drv_uses_atomic_modeset(property->dev) && !(property->flags & DRM_MODE_PROP_IMMUTABLE)) return drm_atomic_get_property(obj, property, val);
