6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ivan Lipski <ivlipski@xxxxxxx>
commit 778e3979c5dc9cbdb5d1b92afed427de6bc483b4 upstream.
[WHY]
This patch is a dupplicate implementation of 14bcf29b, which we
are reverting due to a regression with kms_plane_cursor IGT tests.
This reverts commit 38e6f715b02b572f74677eb2f29d3b4bc6f1ddff.
