[PATCH] usb: typec: tcpm: qcom: fix connector fwnode_handle leak in qcom_pmic_typec_port_probe()

[Selby Mashiki]

In qcom_pmic_typec_port_probe(), device_get_named_child_node(dev,
"connector") acquires a reference to the connector fwnode_handle to pass
to_of_node(connector) to devm_of_regulator_get_optional(), but never
releases the reference.

Call fwnode_handle_put(connector) immediately after
devm_of_regulator_get_optional() to fix the leak.

Fixes: 506927b6bf29 ("usb: typec: tcpm: qcom: prefer VBUS supply from the connector node")
