How about also adding to this:

Fixes: dd08ebf6c352 ("drm/xe: Introduce a new DRM driver for Intel GPUs")
Cc: stable@vger.kernel.org

Otherwise if anyone tries OA on 6.11 (when it appeared) might hit this
issue and start filing bugs etc. So the simplest I think is to add the
above now itself.

Otoh, 6.12 will probably be a LTS kernel and this patch will be there...
