[RFC 2/2] drm/i915: Add protections to sysfs local memory information

[Krzysztof Karas]

Hi Krzysztof,

> check is enforced.
If we decide that this patch is neede, I think we should squash
it with the first one to introduce a mechanism that can already
be secured.

Maybe change that to "intel_memory_info_restrictive"?
"Paranoid" relates to extreme fearfulness/paranoia/anxiety,
which might seem a bit over the top :)

Best Regards,
