From db56f974941b75b2c96e577100e7abe64b03d9b9 Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Fri, 21 Jun 2019 08:08:11 +0100 Subject: [PATCH] drm/i915: Eliminate dual personality of i915_scratch_offset 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.
