From b918c62e086b2130a7bae44110ca516ef10bfe5a Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Thu, 17 May 2012 18:51:11 -0700 Subject: PCI: replace struct pci_bus secondary/subordinate with busn_res Replace the struct pci_bus secondary/subordinate members with the struct resource busn_res. Later we'll build a resource tree of these bus numbers.
