Subject: drm/i915: Reject the pin ioctl on gen6+
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=02f6bcccf7c324115747aae2f0addd6af5d321cd;p=linux-beck.git

drm/i915: Reject the pin ioctl on gen6+

Especially with ppgtt this kinda stopped making sense. And if we
indeed need this to hack around an issue, we need something that also
works for non-root.
