From 9095c86374db8a6b75e0e3398e7c1a9859d6b868 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 15 Feb 2019 10:27:32 +0000 Subject: [PATCH] drm/i915/selftests: Drop unnecessary struct_mutex around i915_reset() Since we no longer need to hold struct_mutex to perform a global device reset, don't do so for igt_reset_wedge().
