3.5.7.22 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Grant Likely <grant.likely@linaro.org>
commit 0640332e073be9207f0784df43595c0c39716e42 upstream.
Any calls to dt_alloc() need to be zeroed. This is a temporary fix, but the allocation function itself needs to zero memory before returning it. This is a follow up to patch 9e4012752, "of: fdt: fix memory initialization for expanded DT" which fixed one call site but missed another.
