Applied to mtd/next, thanks!

[1/1] mtd: parsers: ofpart: fix OF node refcount leak in parse_fixed_partitions()
      commit: 7cce81df7d26d44123bd7620715c8349d96793d7

Patche(s) should be available on mtd/linux.git and will be
part of the next PR (provided that no robot complains by then).

Kind regards,
