The struct drm_dp_desc contains struct drm_dp_dpcd_ident, and the struct drm_dp_dpcd_ident contains the array, so zero-initialization requires a more couple of braces. In the ARM compiler environment, the compile warning pointing it out: drivers/gpu/drm/drm_dp_mst_topology.c: In function 'drm_dp_mst_dsc_aux_for_port': drivers/gpu/drm/drm_dp_mst_topology.c:5494:9: warning: missing braces around initializer [-Wmissing-braces] struct drm_dp_desc desc = { 0 }; Signed-off-by: Tang Bin <tangbin@xxxxxxxxxxxxxxxxxxxx> Signed-off-by: Shengju Zhang <zhangshengju@xxxxxxxxxxxxxxxxxxxx> --- drivers/gpu/drm/drm_dp_mst_topology.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/drm_dp_mst_topology.c b/drivers/gpu/drm/drm_dp_mst_topology.c index 70c4b7a..4d8d1fd 100644 --- a/drivers/gpu/drm/drm_dp_mst_topology.c +++ b/drivers/gpu/drm/drm_dp_mst_topology.c @@ -5494,7 +5494,7 @@ struct drm_dp_aux *drm_dp_mst_dsc_aux_for_port(struct drm_dp_mst_port *port) { struct drm_dp_mst_port *immediate_upstream_port; struct drm_dp_mst_port *fec_port; - struct drm_dp_desc desc = { 0 }; + struct drm_dp_desc desc = { { { 0 } } }; u8 endpoint_fec; u8 endpoint_dsc; -- 2.7.4 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
