Subject: [PATCH 0/3] drm/vkms: Reimplement line-per-line pixel conversion
 for writeback

This series re-introduce the line-by-line algorithm. This is simpler than 
the read part because no rotation/translations are involved. 

PATCH 1/2 is the re-introduction itself
PATCH 2/2 is a proposition to avoid code repetition using a "big" macro.

This series depends on [1].
