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 'program_timing_sync':
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:1409:17: error: 'struct dc_config' has no member named 'use_pipe_ctx_sync_logic'
 1409 |   if (dc->config.use_pipe_ctx_sync_logic) {
      |                 ^

Caused by git doing a bad automatic merge with Linus' tree because commit

  75b950ef6166 ("Revert "drm/amd/display: Fix for otg synchronization logic"")

has been cherry-picked into the amdgpu tree and then a fixed version of
the reverted commit applied on top.  It would be easier if just a
fix up for the oriingal commit was added to the amdgpu tree, or Linus'
tree was merged into the amdgpu tree and then the fixed version applied.

I have used the amdgpu tree from next-20220113 for today.
