+Subject: Revert "drm/amd/display: Add NULL check for 'afb' before dereferencing in amdgpu_dm_plane_handle_cursor_update"
+
+From: Ivan Lipski <ivlipski@amd.com>
+
+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.
