From: Maxime Ripard Date: Mon, 11 Jul 2022 17:39:36 +0000 (+0200) Subject: drm/vc4: perfmon: Add missing mutex_destroy X-Git-Tag: microblaze-v6.2~40^2~22^2~173 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=57d68ee8f719efa05bcec64625a9898231ed43c5;p=linux-2.6-microblaze.git drm/vc4: perfmon: Add missing mutex_destroy vc4_perfmon_open_file() will instantiate a mutex for that file instance, but we never call mutex_destroy () in vc4_perfmon_close_file(). Let's add that missing call.
