device.

External suspend calls should never be allowed to fail in this way,
only autosuspend calls. The driver can tell them apart by checking
the PM_EVENT_AUTO bit in the message.event argument to the suspend
method; this bit will be set for internal PM events (autosuspend) and
clear for external PM events.
only autosuspend calls. The driver can tell them apart by applying
the PMSG_IS_AUTO() macro to the message argument to the suspend
method; it will return True for internal PM events (autosuspend) and
False for external PM events.
