linux-next: build failure after merge of the drm-misc tree

[Stephen Rothwell]

Hi all,

After merging the drm-misc tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/gpu/drm/vmwgfx/vmwgfx_scrn.c: In function 'vmw_sou_crtc_page_flip':
drivers/gpu/drm/vmwgfx/vmwgfx_scrn.c:327:8: error: too few arguments to function 'drm_atomic_helper_page_flip'
  ret = drm_atomic_helper_page_flip(crtc, new_fb, NULL, flags);
        ^
In file included from drivers/gpu/drm/vmwgfx/vmwgfx_scrn.c:31:0:

     ^
drivers/gpu/drm/vmwgfx/vmwgfx_stdu.c: In function 'vmw_stdu_crtc_page_flip':

Caused by commit

  41292b1fa13a ("drm: Add acquire ctx parameter to ->page_flip(_target)")

interacting with commits

  904bb5e5817f ("drm/vmwgfx: Switch over to internal atomic API for STDU")

I added this merge fix patch for today:
