* drm-fbdev-cleanup: drm/fb: remove drm_fb_helper_setcolreg drm/kms/fb: use slow work mechanism for normal hotplug also. drm/kms/fb: add polling support for when nothing is connected. drm/kms/fb: provide a 1024x768 fbcon if no outputs found. drm/kms/fb: separate fbdev connector list from core drm connectors drm/kms/fb: move to using fb helper crtc grouping instead of core crtc list drm/fb: fix fbdev object model + cleanup properly.
