SYSDEV_SUSPEND(9)					   Device drivers infrastructure					 SYSDEV_SUSPEND(9)

NAME
       sysdev_suspend - Suspend all system devices.

SYNOPSIS
       int sysdev_suspend(pm_message_t state);

ARGUMENTS
       state
	   Power state to enter.

DESCRIPTION
       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.
