From e5be5c7a8ffa8471fb31554cf56f3efd11f7e454 Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Fri, 21 Jun 2019 08:07:40 +0100 Subject: [PATCH] drm/i915: Introduce struct intel_gt as replacement for anonymous i915->gt We have long been slighlty annoyed by the anonymous i915->gt. Promote it to a separate structure and give it its own header. This is a first step towards cleaning up the separation between i915 and gt. v2: * Adjust SPDX header.
