Both functions exists, but calling drm_kms_helper_hotplug_event() from this hook would result in an endless loop until we crash somewhere. > * helper of output changes. Ah I meant not just removing this, but explaining what to do now instead. Suggestion: * This hook is deprecated, drivers should instead use * drm_fbdev_generic_setup() which takes care of any necessary * hotplug event forwarding already without further involvement by * the driver. Can you pls respin, with the function change dropped and the fixme replaced with the above?
