This is the 4th revision of the patch.IMHO, no need to add _noirq in both struct and struct members.
+ * struct pm_noirq_ops - device PM callbacks executed with interrupts disabled
+ *
+ * The following callbacks included in 'struct pm_noirq_ops' are executed with
+ * the nonboot CPUs switched off and with interrupts disabled on the only
+ * functional CPU. They also are executed with the PM core list of devices
+ * locked, so they must NOT unregister any devices.
+ *
+ * @suspend_noirq: Complete the operations of ->suspend() by carrying out any
+ * actions required for suspending the device that need interrupts to be
+ * disabled
