Subject: [PATCH 2/3] gpio: sim: switch to device_for_each_child_node_scoped()
Date: Sat, 28 Sep 2024 21:47:36 +0200 [thread overview]
Message-ID: <20240928-gpio_device_for_each_child_node_scoped-v1-2-c20eff315f4f@gmail.com> (raw)
In-Reply-To: <20240928-gpio_device_for_each_child_node_scoped-v1-0-c20eff315f4f@gmail.com>
Switch to device_for_each_child_node_scoped() to simplify the code by
removing the need for a call to fwnode_handle_put() in the error path.
This also prevents possible memory leaks if new error paths are added
without the required call to fwnode_handle_put().
