[drm-tip:drm-tip 1/7] drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_mst_types.c:219:6: error: redefinition of 'dm_dp_mst_dc_sink_create'

[Vivi, Rodrigo]

Drm-tip rebuild created this function duplication in some merge resolution... not sure where that came from or started... But Lucas had warned me yesterday morning...

So, yesterday night I added a fix-up on drm-rerere that remove the duplication on drm-tip... and that should be fixed by now I think...

Could you please fetch and recheck?!

Note: the drm-tip/drm-tip HEAD 16432d39f2cbdc7a8798df3ebb4f7c882fb23132 builds fine.
     It only hurts bisectibility.
