From 586058f2549db835ed5ff5b31f7bc907331fdc97 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2907/4131] drm/amd/display: Program cursor regs after context
swapped.
Cursor is abnormal after pipe_ctx is changed in context.
Cause: cursor attributes is programmed right after front end
programming, but it use old pipe_ctx to program which is not
updated yet.
Solution:
Program cursor regs after context swapped.
