Subject[PATCH 2/2] mn10300/PCI: Remove useless pcibios_last_bus
From
Date
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.
