void* s390_register_adapter_interrupt	(	adapter_int_handler_t	handler,
		void *	drv_data,
		u8	isc
	)

s390_register_adapter_interrupt() - register adapter interrupt handler : adapter handler to be registered : driver data passed with each call to the handler : isc for which the handler should be called

Returns: Pointer to the indicator to be used on success ERR_PTR() if registration failed
