[PATCH 4.9 51/70] MIPS: Octeon: add missing of_node_put()

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicholas Mc Guire <hofrat@xxxxxxxxx>

[ Upstream commit b1259519e618d479ede8a0db5474b3aff99f5056 ]

The call to of_find_node_by_name returns a node pointer with refcount
incremented thus it must be explicitly decremented here after the last
usage.
