[PATCH 5.15 309/667] regulator: pfuze100: Fix refcount leak in pfuze_parse_regulators_dt

[Greg Kroah-Hartman]

From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ Upstream commit afaa7b933ef00a2d3262f4d1252087613fb5c06d ]

of_node_get() returns a node with refcount incremented.
Calling of_node_put() to drop the reference when not needed anymore.

Fixes: 3784b6d64dc5 ("regulator: pfuze100: add pfuze100 regulator driver")
