Ok, so the question would be then why do you not override the value in root->segment then (actually, is it *correct* to leave the segment value in root-> unchanged even if it is overriden) ? Anyway, node is just used for a printk, why do not you add segment and node to acpi_pci_root_info ? Just cosmetic stuff, trying to help you simplify the code, it is not easy to parse.
