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

This pull request includes regression fixups, build warnings, and
   trivial cleanups which mostly remove some codes not used anymore.

* 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
  drm/exynos: Staticize local function in exynos_drm_gem.c
  drm/exynos: fimd: actually disable dp clock
  drm/exynos: dp: remove suspend/resume functions
  drm/exynos: remove unused mode_fixup() code
  drm/exynos: remove decon_mode_fixup()
  drm/exynos: remove fimd_mode_fixup()
  drm/exynos: rotator: Clock control is unused if !PM
  drm/exynos: fimc: Clock control is unused if !PM
  drm/exynos: Suspend/resume is unused if !PM
  drm/exynos: create a fake mmap offset with gem creation
  drm/exynos: remove call to drm_gem_free_mmap_offset()
  drm/exynos: Remove useless EXPORT_SYMBOL_GPLs
  drm/exynos: cleanup line feed in exynos_drm_gem_get_ioctl
  drm/exynos: cleanup function calling written twice
  drm/exynos: staticize exynos_drm_gem_init()
  drm/exynos: remove unnecessary NULL assignment
  drm/exynos: fix missed calling of drm_prime_gem_destroy()
  drm/exynos: fix layering violation of address
