[Intel-gfx] [RFC v4 14/25] drm/fb-helper: Remove struct drm_fb_helper_connector
Noralf Trønnes
noralf at tronnes.org
Fri Apr 13 16:53:43 UTC 2018
No need to maintain a list of registered connectors. Just use the
connector iterator.
TODO: Remove:
- drm_fb_helper_add_one_connector()
- drm_fb_helper_single_add_all_connectors()
- drm_fb_helper_remove_one_connector()
