From d23a6e3f764b69c122fc18537cc73548fdc95939 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ma=C3=ADra=20Canal?= Date: Tue, 8 Nov 2022 14:54:25 -0300 Subject: [PATCH] drm/v3d: add missing mutex_destroy MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit v3d_perfmon_open_file() instantiates a mutex for a particular file instance, but it never destroys it by calling mutex_destroy() in v3d_perfmon_close_file(). Similarly, v3d_perfmon_create_ioctl() instantiates a mutex for a particular perfmon, but it never destroys it by calling mutex_destroy() in v3d_perfmon_destroy_ioctl(). So, add the missing mutex_destroy on both cases.
