From 8885b7b637fa9aca7e1b00581a0173c6956966d3 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 17 Sep 2012 13:22:54 +0200 Subject: PCI: Provide a default pcibios_update_irq() Most architectures implement this in exactly the same way. 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.
