This seems to be a bit misleading. It seems to me that you must cancel
any outstanding request to autosuspend from other layers.

How about something more like this:

*	Resume (return to an operational power level) the specified host,
*	and prevent autosuspends from other software layers until the
*	template autosuspend method has been called again.
*	Return 0 if the resume was successful, otherwise a negative
*	error code.

Who prevents them?  The autoresume() implementation, or its caller?
