sysdev_suspend9
Suspend all system devices.
Usage
int sysdev_suspend(pm_message_t
state);
Arguments
state
Power state to enter.
Overview
We perform an almost identical operation as sysdev_shutdown above, though calling ->suspend instead. Interrupts are disabled when this called. Devices are responsible for both saving state and quiescing or powering down the device.
This is only called by the device PM core, so we let them handle all synchronization.
