int drm_fb_helper_hotplug_event ( struct drm_fb_helper * fb_helper )

drm_fb_helper_hotplug_event - respond to a hotplug notification by probing all the outputs attached to the fb. : the drm_fb_helper

LOCKING: Called at runtime, must take mode config lock.

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

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

	)

drm_helper_initial_config - setup a sane initial connector configuration : DRM device

LOCKING: Called at init time, must take mode config lock.

Scan the CRTCs and connectors and try to put together an initial setup. At the moment, this is a cloned configuration across all heads with a new framebuffer object as the backing store.

RETURNS: Zero if everything went ok, nonzero otherwise.
