Merge tag 'devicetree-fixes-for-3.11' of git://sources.calxeda.com/kernel/linux
Pull device tree fix from Rob Herring:
"For DT unflattening, add missing memory initialization.
This is needed for arches like PPC that use memblock_alloc. This
appears to have been an issue for some time, but is a somewhat limited
usecase of OF_DYNAMIC"
