. pci_reserve() returns an error on devices that have already been reserved, instead of panic()ing; the pci_reserve() library call still panics, pci_reserve_ok() returns an int. . this allows at_wini to use the instance value as intended, as all devices are seen, even reserved ones . only devices actually used by at_wini are pci_reserve()d . pci doesn't release devices based on argv[0], as at_wini both have the same name and multiple instances won't work together properly
