[PATCH 5.19 0487/1157] mediatek: mt76: mac80211: Fix missing of_node_put() in mt76_led_init()
From: Greg Kroah-Hartman

[ Upstream commit 0a14c1d0113f121151edf34333cdf212dd209190 ]
We should use of_node_put() for the reference 'np' returned by
of_get_child_by_name() which will increase the refcount.
Fixes: 17f1de56df05 ("mt76: add common code shared between multiple chipsets")
