[PATCH v3 0/3] drm/vkms: Reimplement line-per-line pixel conversion for writeback

[Louis Chauvet]

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

PATCH 1/3 is the re-introduction itself
PATCH 2/3 is a proposition to avoid code repetition using a "big" macro.
PATCJ 3/3 is the usage of PATCH 2 to support a new format

This series depends on [1].
