Subject: [PATCH 2/2] hwmon: nct7363: Fix a resource leak in nct7363_present_pwm_fanin

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.
