Subject: [PATCH] ia64: Be consistent in the type of the PCI_CONTROLLER() macro argument.

PCI_CONTROLLER() macro in include/asm/pci.h expects an argument "busdev"
which implies a 'struct pci_bus *' type of variable (or at least that
is the type of most of the invocations). Correct the cases where the
macro is called with a 'struct pci_dev *' variable as argument.
