From 92f02430934ca1c1e991a1ab3541880575042697 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Thu, 17 May 2012 18:51:11 -0700 Subject: [PATCH] PCI: add busn_res in struct pci_bus This adds a busn_res resource in struct pci_bus. This will replace the secondary/subordinate members and will be used to build a bus number resource tree to help with bus number allocation.
