From cfa0652c4eb4ca37f88fcdd7d871cf98d9d98c0e Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 7 May 2007 21:51:41 -0700 Subject: [PATCH] [SPARC64] PCI: Use common routine to fetch PBM properties. Namely bus-range and ino-bitmap. This allows us also to eliminate pci_controller_info's pci_{first,last}_busno fields as only the pbm ones are used now. Signed-off-by: David S.
