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.
