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

Hi Rob,

[Dave, this will presumably soon turn up in the drm tree]

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

drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c: In function 'dpu_plane_destroy':
drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c:1483:3: error: too few arguments to function 'drm_plane_helper_disable'
   drm_plane_helper_disable(plane);
   ^~~~~~~~~~~~~~~~~~~~~~~~
In file included from drivers/gpu/drm/msm/msm_drv.h:43:0,
                 from drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c:24:
include/drm/drm_plane_helper.h:72:5: note: declared here
 int drm_plane_helper_disable(struct drm_plane *plane,
     ^~~~~~~~~~~~~~~~~~~~~~~~

Caused by commit

  drm_plane_helper_disable ("drm/msm: Add SDM845 DPU support")

interacting with commit

  070473bcf703 ("drm: add missing ctx argument to plane transitional helpers")

from the drm tree.

I have added this merge fix patch.
