linux-next: build failure after merge of the sunxi tree

[Stephen Rothwell]

Hi all,

After merging the sunxi tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/gpu/drm/sun4i/sun4i_crtc.c: In function 'sun4i_crtc_enable_vblank':
drivers/gpu/drm/sun4i/sun4i_crtc.c:109:31: error: 'struct sun4i_crtc' has no member named 'drv'
  struct sun4i_drv *drv = scrtc->drv;
                               ^
drivers/gpu/drm/sun4i/sun4i_crtc.c: In function 'sun4i_crtc_disable_vblank':
drivers/gpu/drm/sun4i/sun4i_crtc.c:121:31: error: 'struct sun4i_crtc' has no member named 'drv'
  struct sun4i_drv *drv = scrtc->drv;
                               ^

Caused by commit

  50480a78e282 ("drm: sun4i: use vblank hooks in struct drm_crtc_funcs")

from the drm-misc tree interacting with commit

  1b8d109585df ("drm/sun4i: Add backend and tcon pointers to sun4i_crtc")

from the sunxi tree.

I added this merge fix patch:
