+ * The lock is used to serialise management event queue polling

+ * Locks which may be held when the lock is acquired:
+ * - adapter lock, when:
+ * - device start/stop to change mgmt_evq_running
+ * - any control operations in client side MCDI proxy handling to
+ * poll management event queue waiting for proxy response
+ * - MCDI lock, when:
+ * - any control operations in client side MCDI proxy handling to
+ * poll management event queue waiting for proxy response

+ * Locks which are acquired with the lock held:
