From 84f1c1e08906f2206f2bbdd19e4ff6a0757ff7f8 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Mon, 26 May 2008 12:12:30 +1000 Subject: [PATCH] powerpc: Rework ipic_init() so we can avoid freeing the irq_host If we do the call to of_address_to_resource() first, then we don't need to worry about freeing the irq_host (which the code doesn't do currently anyway).
