commit b3fb36ed694b05738d45218ea72cf7feb10ce2b1 upstream.
kmemleak reports several memory leaks from devicetree unittest. This is the fix for problem 1 of 5.
of_unittest_changeset() reaches deeply into the dynamic devicetree functions. Several nodes were left with an elevated reference count and thus were not properly cleaned up. Fix the reference counts so that the memory will be freed.
