CVE-2024-44980: drm/xe: Fix opregion leak
In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Fix opregion leak
Being part o the display, ideally the setup and cleanup would be done by display itself. However this is a bigger refactor that needs to be done on both i915 and xe. For now, just fix the leak:
