2025-12-08drm/amd/display: Fix wrong x_pos and y_pos for cursor offloadNicholas Kazlauskas2-8/+9
[Why] The hubp401_cursor_set_position function programs a different value than it stores for use with cursor offload. This can cause a desync when switching between cursor programming paths. [How] We do the translation to destination space currently twice: once in the HWSS layer, and then again in the HUBP layer since we never store the translated result. HUBP expects to program the pos->x and pos->y directly for other ASIC, so follow that pattern here as well.
