Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux

Browse source 
Pull Exynos DRM changes from Dave Airlie:
 "So I totally missed Inki's pull request for -next, its fully exynos
  self contained."

(I took just the actual commits, not Dave's two extraneous merges)

* 'drm-next' of git://people.freedesktop.org/~airlied/linux: (30 commits)
  drm/exynos: fixed exception to page allocation failure
  drm/exynos: use __free_page() to deallocate memory
  drm/exynos: fixed a comment to gem size.
  drm/exynos: removed unnecessary variable
  drm/exynos: do not release memory region from exporter.
  drm/exynos: set buffer type from exporter.
  drm/exynos: use alloc_page() to allocate pages.
  drm/exynos: fixed build warning.
  drm/exynos: fixed edid data setting at vidi connection request
  drm/exynos: check if raw edid data is fake or not for test
  drm/exynos: set edid fake data only for test.
  drm/exynos: removed unnecessary declaration.
  drm/exynos: fix buffer pitch calculation
  drm/exynos: check for null in return value of dma_buf_map_attachment()
  drm/exynos: return NULL if exynos_pages_to_sg fails
  drm/exynos: Use devm_* functions in exynos_mixer.c
  drm/exynos: Use devm_* functions in exynos_hdmi.c
  drm/exynos: Use devm_* functions in exynos_drm_fimd.c
  drm/exynos: Add missing static storage class specifier
  drm/exynos: add property for crtc mode
