armada_pitch() does have some special alignment (it aligns the pitch to
128 bytes). I've no idea what drm_mode_size_dumb() does. Can you check
whether it does the same please?
If it doesn't, then this patch is incorrect.
Indeed, I should have noticed. Will be fixed in the next iteration.
Thanks for the review.
Best regards
Thomas
