[Qemu-devel] [PATCH] qom: cpu: destroy work_mutex in cpu_common_finalize

[Li Qiang <liq3ea@163.com>]

Commit 376692b9dc6(cpus: protect work list with work_mutex)
initialize a work_mutex in cpu_common_initfn, however forget
to destroy it. This will cause resource leak when hotunplug cpu
or hotplug cpu fails.
