This seem like a valid concern from readability and maintainability 
standpoint. My patch was aimed mostly at performance and maintainability 
using tools: some more pedantic analyzers are sensitive to non-checked 
return values (as of now, drm_rect_intersect is ignored).

Would it be a better idea to make an update to the patch with second 
drm_rect_visible call changed to an appropriately named state flag set 
with drm_rect_intersect result?

BTW, the original patch somehow got mangled while it made its way to the 
patchwork: source list line in patch got broken, which permits the patch 
from being applied (the original version did not have that line break). 
Any ideas how to prevent this happening with the second version of patch 
(in case the idea is viable)?
