From 3ddbebf878ac8d958bb34e87a742a6b3adc283a3 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 17 Sep 2012 13:22:53 +0200 Subject: PCI: Discard __init annotations for pci_fixup_irqs() and related functions 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.

Instead of having each architecture duplicate this function, provide a single implementation in the core and make it a weak symbol so that it can be overridden on architectures where it is required.
