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")

Hello Selby,

check out

https://lore.kernel.org/linux-arm-msm/20261025-typec-of-fix-v1-1-06bfc16a7846@ixit.cz/

This is one of the patches from the gen1 Type-C enablement series and it seems 
to be almost same as yours, if it looks good to you, feel free to drop A-b/R-b.

Thanks
David
