[PATCH] MIPS: Squash pci_fixup_irqs() compiler warning

[Kevin Cernekee]

MIPS Linux is unique in that it uses a "const struct pci_dev *" argument
to discourage bad coding practices in pcibios_map_irq().  Add a cast so
that this warning goes away:

arch/mips/pci/pci.c: In function 'pcibios_init':
arch/mips/pci/pci.c:165:45: warning: passing argument 2 of 'pci_fixup_irqs' from incompatible pointer type
include/linux/pci.h:856:6: note: expected 'int (*)(struct pci_dev *, u8,  u8)' but argument is of type 'struct pci_dev *'

It's been two years since the original discussion, and the warning is
still there.  It is now the only warning left in my kernel build.

I was hoping we could get this resolved for good (one way or another).
