Hi Daniel,
I have checked make htmldocs on v2 of this patch. I have attached output drm-kms.html on that thread. No indentation issue is observed. Attached again for reference. Can you please provide RB on that?
Regards Pratik

Add reverse iterator "for_each_oldnew_plane_in_state_reverse" to complement "for_each_oldnew_plane_in_state" way of reading plane states.
The plane states are required to be read in reverse order for amdgpu, as the z order convention followed in linux is opposite to how the planes are supposed to be presented to DC engine, which is in common to both windows and linux.

Makes sense.

Are you sure this renders correctly in kernel-doc? Iirc you have to indent the continuation line.
Assuming this is fixed:
