Frank Rowand 0773dcee66 of: overlay: add_changeset_property() memory leak 
[ Upstream commit 637392a850 ]

No changeset entries are created for #address-cells and #size-cells
properties, but the duplicated properties are never freed.  This
results in a memory leak which is detected by kmemleak:

 unreferenced object 0x85887180 (size 64):
   backtrace:
     kmem_cache_alloc_trace+0x1fb/0x1fc
     __of_prop_dup+0x25/0x7c
     add_changeset_property+0x17f/0x370
     build_changeset_next_level+0x29/0x20c
     of_overlay_fdt_apply+0x32b/0x6b4
     ...
