Merge tag 'exynos-drm-fixes-for-v4.17-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

Remove Exynos specific framebuffer structure and
relevant functions.
- it removes exynos_drm_fb structure which is a wrapper of
  drm_framebuffer and unnecessary two exynos specific callback
  functions, exynos_drm_destory() and exynos_drm_fb_create_handle()
  because we can reuse existing drm common callback ones instead.

* tag 'exynos-drm-fixes-for-v4.17-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
  drm/exynos: exynos_drm_fb -> drm_framebuffer
  drm/exynos: Move dma_addr out of exynos_drm_fb
  drm/exynos: Move GEM BOs to drm_framebuffer
  drm/amdkfd: Deallocate SDMA queues correctly
  drm/amdkfd: Fix scratch memory with HWS enabled
