[Intel-gfx] [PATCH v5 2/6] drm/i915/pxp: add device link between i915 and mei_pxp

[Teres Alexis, Alan Previn]

Thanks for reviewing the patch. I will fix the code according to your recommendation.
I assume we could probably go with -ENOLINK as the error (instead of -ENOMEM).
However, i'll wait for Alexander to respond on whether he needs drm_WARN_ON and your question on RPM.
