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

Hi all,

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

drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c: In function 'process_deferred_updates':
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:1808:21: error: 'struct dc' has no member named 'dcn_ip'
 1808 |   for (i = 0; i < dc->dcn_ip->max_num_dpp; i++)
      |                     ^~

Caused by commit

  bfd34644dedb ("drm/amd/display: Defer LUT memory powerdown until LUT bypass latches")

CONFIG_DRM_AMD_DC_DCN is not set for this build.

I have used the amdgpu tree from next-20210928 for today.
