Hi all,

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

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:4031:18: error: initialization of 'int (*)(struct drm_connector *, struct drm_atomic_state *)' from incompatible pointer type 'int (*)(struct drm_connector *, struct drm_connector_state *)' [-Werror=incompatible-pointer-types]
  .atomic_check = amdgpu_dm_connector_atomic_check,
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:4031:18: note: (near initialization for 'amdgpu_dm_connector_helper_funcs.atomic_check')

Caused by commit

  6f3b62781bbd ("drm: Convert connector_helper_funcs->atomic_check to accept drm_atomic_state")

interacting with commit

  88694af9e4d1 ("drm/amd/display: Expose HDR output metadata for supported connectors")

from the drm tree.

I added the following merge fix patch:

From: Stephen Rothwell <>
Date: Fri, 14 Jun 2019 14:27:12 +1000
Subject: [PATCH] fixup for "drm: Convert connector_helper_funcs->atomic_check
 to accept drm_atomic_state"
