When fixing up the kernels state nodes we depended on the full node path of the input device tree. This does not work when the kernel device tree has different names. This has happened lately when the i.MX6 device trees got their leading zeroes removed from the node names. Use of_find_node_by_reproducible_name() to find the node corresponding to the storage backend node in the kernel device tree.
