Two small changes, one getting rid of the bogus gamma table size and
another removing Terje from the MAINTAINERS file since he no longer does
any work on host1x or display.

* tag 'drm/tegra/for-4.7-rc1' of git://anongit.freedesktop.org/tegra/linux:
  MAINTAINERS: Remove Terje Bergström as Tegra DRM maintainer
  drm/tegra: Don't set a gamma table size

Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

 Summary:
   - expose HDMI-PHY clock to other drivers.
     . this patch was included in below patch series but I missed.
             http://www.spinics.net/lists/dri-devel/msg103097.html
   - some fixups about DECON5433 driver
     . this patch corrects vblank handling and fixes up trigger
       configuration.
   - use generic functions - gem_prime_mmap and dma_buf_mmap.
   - use DMA-Mapping API instead of specific one.
   - some code cleanups and fixeups.

* 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
  drm/exynos/decon5433: fix trigger configuration
  drm/exynos/dsi: use of_graph_get_endpoint_by_regs helper
  drm/exynos/dpi: use of_graph_get_endpoint_by_regs helper
  drm/exynos: Nuke dummy fb->dirty callback
  drm/exynos: use directly DMA mapping APIs on g2d
  drm/exynos/hdmi: Don't print error on deferral due to regulators
  drm/exynos: fix imported dma-buf to be mapped
  drm/exynos: support gem_prime_mmap
  drm/exynos: fimd: harden fimd_calc_clkdiv()
  drm/exynos: fix cancel page flip code
  drm/exynos/decon5433: do not use unnecessary software trigger
  drm/exynos/decon5433: handle vblank in vblank interrupt
  drm/exynos/hdmi: expose HDMI-PHY clock as pipeline clock

Actually, pp_sw_init executes pptable_init and backend_init orderly if
they are initialized successfully. So rewrite it to make code more
readable.

just move vm field to job.

so it can get vm from job->vm.

This patch fixed the bellow no DRM_INFO is printed issue:

if (!delay_count)
	DRM_INFO("phylock and phystopstateclklane is not ready.\n");

There will some printed issues with above info, under certain
circumstances:

If ((BIT(0) | BIT(2)) & val) is never true, break will not happen and
delay_count will be max u32 value (?), and no DRM_INFO is printed.

Also if ((BIT(0) | BIT(2)) & val) is true at the last possible
loop round, break happens, but now delay_count is already zero
( because of earlier delay_count-- ) and DRM_INFO is erroneously
printed.
