5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Liang He <windhl@xxxxxxx>
[ Upstream commit db6aee6083a56ac4a6cd1b08fff7938072bcd0a3 ]
In i2c_mux_gpio_probe_fw(), we should add fwnode_handle_put()
when break out of the iteration device_for_each_child_node()
as it will automatically increase and decrease the refcounter.
Fixes: 98b2b712bc85 ("i2c: i2c-mux-gpio: Enable this driver in ACPI land")
