[PATCH] powerpc: Fix search for the main interrupt controller
At present, we are not looking at all interrupt controller nodes in the device tree even though the proper node was not found. This is causing the system panic. The attached patch will scan all nodes until it finds the proper interrupt controller type. Signed-off-by: Haren Myneni <haren@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
