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?

The autoresume implementation.  This comment explains what the function 
is supposed to do, not what its caller does.
