6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Melissa Wen <mwen@xxxxxxxxxx> [ Upstream commit 737222cebecbdbcdde2b69475c52bcb9ecfeb830 ] [why & how] 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.
