From fc825db933657faeac25143ac6c74b57d80f8cf5 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2908/4131] drm/amd/display: Cache cursor position.
When programming cursor position after front end programmed,
if position is already set previously, it doesn't make sense
to program position with all 0.
Cache position and use the parameter after front end programming.
