From 29d88083d6ff697cedf918efd927d2dfff0bf9c4 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Sat, 23 Jan 2021 14:55:43 +0000 Subject: drm/i915/gem: Move freeze/freeze_late next to suspend/suspend_late Push the hibernate pm routines next to the suspend pm routines in gem/i915_gem_pm.c. This has the side-effect of putting the wbinvd() abusers next to each other.
