[PATCH 4.14 029/193] PM / OPP: Add missing of_node_put(np)

[Greg Kroah-Hartman]

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

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

From: Tobias Jordan <Tobias.Jordan@xxxxxxxxxxxxxx>

commit 7978db344719dab1e56d05e6fc04aaaddcde0a5e upstream.

The for_each_available_child_of_node() loop in _of_add_opp_table_v2()
doesn't drop the reference to "np" on errors. Fix that.

Fixes: 274659029c9d (PM / OPP: Add support to parse "operating-points-v2" bindings)
