      drm/atomic: fix null pointer access to mode_fixup callback · 84524917
      Inki Dae authored
      This patch fixes null pointer access incurred when
      encoder driver didn't set its own mode_fixup callback.
      
      mode_fixup callback shoudn't be called if the callback
      of drm_encoder_helper_funcs is NULL.
      
      Changelog v2:
      - change it to else if

      drm/i915: Use CONFIG_DRM_FBDEV_EMULATION · 0695726e
      Daniel Vetter authored
      Instead of our own duplicated one. This fixes a bug in the driver
      unload code if DRM_FBDEV_EMULATION=n but DRM_I915_FBDEV=y because we
      try to unregister the nonexistent fbdev drm_framebuffer.

      drm/core: Set mode to NULL when connectors in a set drops to 0. · cebbb739
      Maarten Lankhorst authored
      Without this when a MST connector is removed drm_atomic_helper_set_config
      can complain about set->mode && !set->num_connectors.
