Subject: RE: [PATCH] drm/atomic: Add new reverse iterator over all plane state

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
