I suppose having the core use only the name would be a bit radical;
but on the other hand, I really like the resulting notion that the
generic code must accordingly know *NOTHING* about the semantics
of any such states. Having a struct sort of begs that it someday
be expanded.

And conceptually "typedef struct pm_sleep_state *suspend_state_t;"?
Though eventually "suspend_state_t" should vanish.
