From 52964f87c64e6c6ea671b5bf3030fb1494090a48 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 28 Aug 2007 18:47:54 +1000 Subject: [POWERPC] Add an optional device_node pointer to the irq_host The majority of irq_host implementations (3 out of 4) are associated with a device_node, and need to stash it somewhere. Rather than having it somewhere different for each host, add an optional device_node pointer to the irq_host structure.
