#1207338 — linux-next: build warnings after merge of the drm-misc tree

Hi all,

After merging the drm-misc tree, today's linux-next build (arm
multi_v7_defconfig) produced these warnings:

drivers/gpu/drm/exynos/exynos_drm_drv.c:290:2: warning: initialization from incompatible pointer type
  .get_vblank_counter = drm_vblank_count,
  ^
drivers/gpu/drm/exynos/exynos_drm_drv.c:290:2: warning: (near initialization for 'exynos_drm_driver.get_vblank_counter')
drivers/gpu/drm/rcar-du/rcar_du_drv.c:262:2: warning: initialization from incompatible pointer type
  .get_vblank_counter = drm_vblank_count,
  ^
drivers/gpu/drm/rcar-du/rcar_du_drv.c:262:2: warning: (near initialization for 'rcar_du_driver.get_vblank_counter')
drivers/gpu/drm/msm/msm_drv.c:981:2: warning: initialization from incompatible pointer type
  .get_vblank_counter = drm_vblank_count,
  ^
drivers/gpu/drm/msm/msm_drv.c:981:2: warning: (near initialization for 'msm_driver.get_vblank_counter')

Introduced by commit

  b90180b057f7 ("drm/irq: More pipe/crtc consistency cleanups")

Yes, that patch turned out to be incomplete. Daniel suggested to remove
it from drm-misc for now and I'll address this fully in a larger patch
for 4.4.
