NAME
       drm_fb_helper_hotplug_event - respond to a hotplug notification by probing all the outputs attached to the fb

SYNOPSIS
       int drm_fb_helper_hotplug_event(struct drm_fb_helper * fb_helper);

ARGUMENTS
       fb_helper
	   the drm_fb_helper

DESCRIPTION
       Scan the connectors attached to the fb_helper and try to put together a setup after *notification of a change in output configuration.

       Called at runtime, takes the mode config locks to be able to check/change the modeset configuration. Must be run from process context
       (which usually means either the output polling work or a work item launched from the driver's hotplug interrupt).

       Note that the driver must ensure that this is only called _after_ the fb has been fully set up, i.e. after the call to
       drm_fb_helper_initial_config.

RETURNS
       0 on success and a non-zero error code otherwise.
