Grant,
This breaks powerpc chroma_defconfig in next-20121127 with:
arch/powerpc/sysdev/scom.c:160:17: error: assignment discards 'const' qualifier from pointer target type [-Werror]
The following fixes it. The change is to generic code, so I'm not sure
it's the right fix as it may break other configs/archs.
