[patch 032/104] PCI, PCI Hotplug: introduce slot_name helpers

[Greg KH]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Alex Chiang <achiang@xxxxxx>

commit 0ad772ec464d3fcf9d210836b97e654f393606c4 upstream

In preparation for cleaning up the various hotplug drivers
such that they don't have to manage their own 'name' parameters
anymore, we provide the following convenience functions:

	pci_slot_name()
	hotplug_slot_name()

These helpers will be used by individual hotplug drivers.
