+Subject: [PATCH] remoteproc: stm32_rproc: Add mutex protection for workqueue
+Git-commit: 35bdafda40cc343ad2ba2cce105eba03a70241cc
+Patch-mainline: v6.4-rc1
+References: git-fixes
+
+The workqueue may execute late even after remoteproc is stopped or
+stopping, some resources (rpmsg device and endpoint) have been
+released in rproc_stop_subdevices(), then rproc_vq_interrupt()
+accessing these resources will cause kernel dump.
