From e00e57efa3448b18c0deedce32732e28683cb73d Mon Sep 17 00:00:00 2001 From: Kenji Kaneshige Date: Fri, 25 Nov 2005 12:21:25 +0900 Subject: [PATCH] shpchp: replace pci_find_slot() with pci_get_slot() This patch replaces pci_find_slot() with pci_get_slot() in the SHPCHP driver. This enables SHPCHP driver to work on multiple PCI segment systems.
