From fb9cfb28bdde57f49137d76e7a54dbd61206d337 Mon Sep 17 00:00:00 2001 From: Liang He Date: Wed, 22 Mar 2023 12:29:51 +0800 Subject: [PATCH] i2c: mux: gpio: Add missing fwnode_handle_put() [ 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.
