From dd952cbb3dae9ea2dc47cc902b796e1e2bf806f0 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Sun, 21 Dec 2008 02:54:27 -0700 Subject: [PATCH] powerpc/mpc5200: Make internal 5200 PIC the default interrupt controller The MPC5200 internal interrupt controller setup function needs to set the default interrupt controller when it is called. Without this irq_create_of_mapping() cannot be called without first determining the pointer to the irq controller (ie. call with controller = NULL).
