Thierry Reding - Sept. 17, 2012, 11:22 a.m.
Remove the __init annotations in order to keep pci_fixup_irqs() around
after init (e.g. for hotplug). This requires the same change for the
implementation of pcibios_update_irq() on all architectures. While at
it, all __devinit annotations are removed as well, since they will be
useless now that HOTPLUG is always on.

Changes in v2:
- remove __init and __devinit annotations altogether

I applied these (both 1/2 and 2/2) to my "next" branch.  Thanks!
