[Intel-gfx] [RFC 33/33] drm/i915: Eliminate dual personality of i915_scratch_offset
Tvrtko Ursulin

Mon Jun 17 18:12:36 UTC 2019
From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>
Scratch vma lives under gt but the API used to work on i915. Make this
consistent by renaming the function to intel_gt_scratch_offset and make
it take struct intel_gt.
v2:
* Move to intel_gt. (Chris)
