From 57d68ee8f719efa05bcec64625a9898231ed43c5 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Mon, 11 Jul 2022 19:39:36 +0200 Subject: [PATCH] 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.
