Inki writes:
Includes bug fixes and code cleanups.
And it considers some restrictions to G2D hardware.
With this, the malfunction and page fault issues to g2d driver
would be fixed.

* 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
  drm/exynos: Check g2d cmd list for g2d restrictions
  drm/exynos: Add a new function to get gem buffer size
  drm/exynos: Deal with g2d buffer info more efficiently
  drm/exynos: Clean up some G2D codes for readability
  drm/exynos: Fix G2D core malfunctioning issue
  drm/exynos: clear node object type at gem unmap
  drm/exynos: Fix error routine to getting dma addr.
  drm/exynos: Replaced kzalloc & memcpy with kmemdup
  drm/exynos: fimd: calculate the correct address offset
  drm/exynos: Make mixer_check_timing static
  drm/exynos: modify the compatible string for exynos fimd
