From 9e2c12988bebca7b99c0cd064b23fb7ea6643c86 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Thu, 13 Dec 2012 01:16:24 +0100 Subject: PPC: e500: pci: Export slot2irq calculation We need the calculation method to get from a PCI slot ID to its respective interrupt line twice. Once in the internal map function and once when assembling the device tree. So let's extract the calculation to a separate function that can be called by both users.
