  and anyone else I've forgotten to make this happen.
- roll out fbdev helper ops to drivers (Stefan Christ)
- last bits of drm_crtc split-up&kerneldoc
- some drm_irq.c crtc functions cleanup
- prepare_fb helper for cma, works correctly with explicit fencing (Marek
  Vasut)
- misc small patches all over
