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

Pull drm fixes from Dave Airlie:
 "Intel, radeon and exynos fixes.  Nothing too major or wierd: one dmar
  fix and a radeon cursor corruption, along with misc exynos fixes."

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: (21 commits)
  drm/exynos: add check for the device power status
  drm/exynos: Make 'drm_hdmi_get_edid' static
  drm/exynos: fimd and ipp are broken on multiplatform
  drm/exynos: don't include plat/gpio-cfg.h
  drm/exynos: Remove "internal" interrupt handling
  drm/exynos: Add missing static specifiers in exynos_drm_rotator.c
  drm/exynos: Replace mdelay with usleep_range
  drm/exynos: Make ipp_handle_cmd_work static
  drm/exynos: Make g2d_userptr_get_dma_addr static
  drm/exynos: consider DMA_NONE flag to dmabuf import
  drm/exynos: free sg object if dma_map_sg is failed
  drm/exynos: added validation of edid for vidi connection
  drm/exynos: let drm handle edid allocations
  drm/radeon: Enable DMA_IB_SWAP_ENABLE on big endian hosts.
  drm/radeon: fix a rare case of double kfree
  radeon_display: Use pointer return error codes
  drm/radeon: fix cursor corruption on DCE6 and newer
  drm/i915: dump UTS_RELEASE into the error_state
  iommu/intel: disable DMAR for g4x integrated gfx
  drm/i915: GFX_MODE Flush TLB Invalidate Mode must be '1' for scanline waits
