From 82b2521d257b5c0efd51821cf5fa306e53bbb6ba Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Tue, 19 Jun 2012 20:01:45 +0000 Subject: [PATCH] powerpc: Fix uninitialised error in numa.c chroma_defconfig currently gives me this with gcc 4.6: arch/powerpc/mm/numa.c:638:13: error: 'dm' may be used uninitialized in this function [-Werror=uninitialized] It's a bogus warning/error since of_get_drconf_memory() only writes it anyway.
