drm/fb-helper: Propagate errors from initial config failure

2015-01-21T13:57:03Z

Make drm_fb_helper_initial_config() return an int rather than a bool so that the error can be properly propagated. While at it, update drivers to propagate errors further rather than just ignore them. v2: - cirrus: No cleanup is required, the top-level cirrus_driver_load() will do it as part of cirrus_driver_unload() in its cleanup path.

drm: Introduce drm_fb_helper_prepare()

2014-07-08T01:31:28Z

To implement hotplug detection in a race-free manner, drivers must call drm_kms_helper_poll_init() before hotplug events can be triggered. Such events can be triggered right after any of the encoders or connectors are initialized. At the same time, if the drm_fb_helper_hotplug_event() helper is used by a driver, then the poll helper requires some parts of the FB helper to be initialized to prevent a crash. At the same time, drm_fb_helper_init() requires information that is not necessarily available at such an early stage (number of CRTCs and connectors), so it cannot be used yet. Add a new helper, drm_fb_helper_prepare(), that initializes the bare minimum needed to allow drm_kms_helper_poll_init() to execute and any subsequent hotplug events to be processed properly.
