From 3749c51ac6c1560aa1cb1520066bed84c6f8152a Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Sun, 13 Dec 2009 08:11:32 -0500 Subject: PCI: Make current and maximum bus speeds part of the PCI core Move the max_bus_speed and cur_bus_speed into the pci_bus. Expose the values through the PCI slot driver instead of the hotplug slot driver. Update all the hotplug drivers to use the pci_bus instead of their own data structures.
