Dear Developers for DRM PANEL DRIVERS, We are developing a static analyzer for Linux Kernel, and we are curious about the function drm_mode_duplicate() in hx83102_get_modes(). https://elixir.bootlin.com/linux/v6.12-rc2/source/drivers/gpu/drm/panel/panel-himax-hx83102.c#L567 ``` struct drm_display_mode *mode; mode = drm_mode_duplicate(connector->dev, m); mode->type = DRM_MODE_TYPE_DRIVER | DRM_MODE_TYPE_PREFERRED; ``` drm_mode_duplicate() will return NULL if it fails to allocate memory, so NULL check is necessary for this function. Directly accessing 'mode->type' may lead to NULL Pointer Dereference. Please kindly correct us if we missed any key information. Looking forward to your response! We can help provide a patch if it's a true bug. Best regards, Zichen
