6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ian Forbes <ian.forbes@xxxxxxxxxxxx>
commit 782e5e7925880f737963444f141a0320a12104a5 upstream.
Legacy DU was broken by the referenced fixes commit because the placement
and the busy_placement no longer pointed to the same object. This was later
fixed indirectly by commit a78a8da51b36c7a0c0c16233f91d60aac03a5a49
("drm/ttm: replace busy placement with flags v6") in v6.9.
Fixes: 39985eea5a6d ("drm/vmwgfx: Abstract placement selection")
