Subject: [PATCH] PCI Hotplug: use bus_slot number for name
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1248d636122e4ec9d7802b850904e3bb48a0da23;p=deliverable%2Flinux.git

[PATCH] PCI Hotplug: use bus_slot number for name

For systems with multiple hotplug controllers, you need to use more than
just the slot number to uniquely name the slot.  Without a unique slot
name, the pci_hp_register() will fail.  This patch adds the bus number
to the name.
