Subject: drm/amd/display: fix cursor offset on rotation 180
From: Melissa Wen <mwen@xxxxxxxxxx>
commit 49d0555976f0972af68397ed996375c135b38ba7 upstream.
Cursor gets clipped off in the middle of the screen with hw rotation
180. Fix a miscalculation of cursor offset when it's placed near the
edges in the pipe split case.
Cursor bugs with hw rotation were reported on AMD issue tracker:
https://gitlab.freedesktop.org/drm/amd/-/issues/2247
The issues on rotation 270 was fixed by:
https://lore.kernel.org/amd-gfx/20221118125935.4013669-22-Brian.Chang@xxxxxxx/
that partially addressed the rotation 180 too. So, this patch is the
final bits for rotation 180.
