[Intel-gfx] [PATCH] drm/i915/selftests: Push the fake iommu device from the stack to data

[Intel-gfx] [PATCH] drm/i915/selftests: Push the fake iommu device from the stack to data

[Chris Wilson]

Since we store a pointer to the fake iommu device that is allocated on
the stack, as soon as we leave the function it goes out of scope and any
future dereference is undefined behaviour. Just in case we may need to
look at the fake iommu device after initialiation, move the allocation
from the stack into the data.
