[PULL 01/30] migration/dirtyrate: Do not unlock cpu_list lock twice

Posted by Philippe Mathieu-Daudé 3 weeks ago

&qemu_cpu_list_lock is locked within the WITH_QEMU_LOCK_GUARD()
context, then unlocked. No need to manually unlock it.

Fixes: 370ed600296 ("cpu: expose qemu_cpu_list_lock for lock-guard use")
