drm_calloc_large: check right size, check integer overflow, use GFP_ZERO
drm: Eliminate magic I2C frobbing when reading EDID
drm/i915: duplicate desired mode for use by fbcon.
drm/via: vfree() no need checking before calling it
drm: Replace DRM_DEBUG with DRM_DEBUG_DRIVER in i915 driver
drm: Replace DRM_DEBUG with DRM_DEBUG_MODE in drm_mode
drm/i915: Replace DRM_DEBUG with DRM_DEBUG_KMS in intel_sdvo
drm/i915: replace DRM_DEBUG with DRM_DEBUG_KMS in intel_lvds
drm: add separate drm debugging levels
radeon: remove _DRM_DRIVER from the preadded sarea map
drm: don't associate _DRM_DRIVER maps with a master
drm: simplify kcalloc() call to kzalloc().
intelfb: fix spelling of "CLOCK"
drm: fix LOCK_TEST_WITH_RETURN macro
drm/i915: Hook connector to encoder during load detection (fixes tv/vga detect)
