16 We perform an almost identical operation as sysdev_shutdown above,
17 though calling ->suspend instead. Interrupts are disabled when this
18 called. Devices are responsible for both saving state and quiescing or
19 powering down the device.

21 This is only called by the device PM core, so we let them handle all
22 synchronization.
