Subject[PATCH v6-resend 06/17] PCI, PCI Hotplug: introduce slot_name helpers
Date
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.
