    Subject[PATCH 063/104] of: Fix missing memory initialization on FDT unflattening
    Date
    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.
