[PATCH 2/2] mn10300/PCI: Remove useless pcibios_last_bus

From: Bjorn Helgaas
Date: Tue Oct 22 2013 - 23:24:23 EST


pcibios_last_bus was apparently copied from x86. On mn10300, it is
statically initialized to -1 and may be set with the "pci=lastbus=<X>"
boot option, but it is never tested. This patch removes everything
related to pcibios_last_bus.
