Revision 280d479b310298dfeb1d6f9a1617eca37beb6ce4 authored by Chris Wilson on 22 December 2018, 03:06:23 UTC, committed by Jani Nikula on 10 January 2019, 13:09:51 UTC
If we fail to pin the ggtt vma slot for the ppgtt page tables, we need
to unwind the locals before reporting the error. Or else on subsequent
attempts to bind the page tables into the ggtt, we will already believe
that the vma has been pinned and continue on blithely. If something else
should happen to be at that location, choas ensues.

Fixes: a2bbf7148342 ("drm/i915/gtt: Only keep gen6 page directories pinned while active")
