+From 0a173fb0be839c92ad355ce06cff8edb76e25b5b Mon Sep 17 00:00:00 2001

+Subject: [PATCH 1813/2940] drm/amd/display: Allow cursor position when
+ plane_res.ipp is NULL
+
+[Why]
+Starting with DCN1, the input_pixel_processor (ipp) struct has been
+replaced by dpp struct (part of DAL3.1 SW architecture change).
+Need to update logic to handle cases where ipp is never allocated.
+
+[How]
+Only skip cursor position programming if both ipp and dpp resources
+are NULL.
