From ba4c0ff47ee098c8e17d25f9dc050e6276bf9979 Mon Sep 17 00:00:00 2001 From: Sunil Khatri Date: Tue, 19 May 2026 15:12:42 +0530 Subject: [PATCH] drm/amdgpu/userq: Fix the mutex_init cleanup for fence_drv_lock MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit mutex fence_drv_lock is destroyed in amdgpu_userq_fence_driver_free also in one of the jump condition mutex_destroy is also called leading to double mutex_destroy. So rearranging the code so amdgpu_userq_fence_driver_free takes care of the clean up along with mutex_destroy.
