From 7c55175b686f4227648acc67aa71d4996561884e Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Fri, 21 Jun 2019 08:07:56 +0100 Subject: [PATCH] drm/i915: Compartmentalize i915_ggtt_probe_hw Having made start to better code compartmentalization by introducing struct intel_gt, continue the theme elsewhere in code by making functions take parameters take what logically makes most sense for them instead of the global struct drm_i915_private.
