From 997526db9fa408058f23de19c0e12abd9207276b Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Mon, 26 May 2008 12:12:30 +1000 Subject: [PATCH] powerpc: Rework Axon MSI setup so we can avoid freeing the irq_host If we do the call to irq_of_parse_and_map() first, then we don't need to worry about freeing the irq_host.
