hm, that's all a bit strange. It would be better to do the request_region() just once and if that works, retain the reservation rather than releasing and reacquiring it.
That being said, the code you've modified is disabled due to !defined(PnPWakeup), and the chances of anyone ever changing that are close to zero. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
