Hello Maxime Ripard,
The patch 03c4c71d25b4: "drm: sun4i: Add composite output" from Oct 29, 2015, leads to the following static checker warning:
drivers/gpu/drm/sun4i/sun4i_tv.c:513 sun4i_tv_comp_get_modes() error: potential null dereference 'mode'. (drm_mode_create returns null)
drivers/gpu/drm/sun4i/sun4i_tv.c 505 static int sun4i_tv_comp_get_modes(struct drm_connector *connector) 506 { 507 int i; 508 509 for (i = 0; i < ARRAY_SIZE(tv_modes); i++) { 510 struct drm_display_mode *mode = drm_mode_create(connector->dev); ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 511 struct tv_mode *tv_mode = &tv_modes[i]; 512 513 strcpy(mode->name, tv_mode->name); ^^^^^^^^^^ 514 515 sun4i_tv_mode_to_drm_mode(tv_mode, mode); 516 drm_mode_probed_add(connector, mode); 517 } 518 519 return i; 520 }
