[PATCH v4.9] PM / OPP: Add missing of_node_put(np)

[PATCH v4.9] PM / OPP: Add missing of_node_put(np)

[Viresh Kumar]

From: Tobias Jordan <Tobias.Jordan@elektrobit.com>

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)
Cc: 4.9 <stable@vger.kernel.org> # 4.9
