From 2c7487a524147f7a3f588c1394be44149f66da94 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 9 Sep 2016 14:11:48 +0100 Subject: drm/i915: Drop local struct_mutex around intel_init_emon[ilk] Access to intel_init_emon() is strictly ordered by gt_powersave, using struct_mutex around it is overkill (and will conflict with the caller holding struct_mutex themselves).
