[PATCH 6.19 233/844] hwmon: (nct7363) Fix a resource leak in nct7363_present_pwm_fanin

[Sasha Levin]

From: Felix Gu <gu_0233@xxxxxx>

[ Upstream commit 4923bbff0bcffe488b3aa76829c829bd15b02585 ]

When calling of_parse_phandle_with_args(), the caller is responsible
to call of_node_put() to release the reference of device node.
In nct7363_present_pwm_fanin, it does not release the reference,
causing a resource leak.
