The declaration of intel_aet_get_events() was removed,
and the function definition still remains in intel_aet.c.
Not sure if this will trigger a warning like
"no user for intel_aet_get_events". Since intel_aet_get_events() is
renamed to static get_events() in a subsequent patch,
perhaps we can mark intel_aet_get_events() as static in
this patch too?

thanks,
