From 8649187a9520f61b742c85f5d313ad89617d86fe Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Fri, 21 Jun 2019 08:07:54 +0100 Subject: [PATCH] drm/i915: Move intel_engines_resume into common init Since this part still operates on i915 and not intel_gt, move it to the common (top-level) function.
