Subject: [PATCH v4 10/15] iio: adc: ti-ads1015: Use device_for_each_child_node_scoped()
Date: Sat, 17 Feb 2024 16:42:44 +0000	[thread overview]
Message-ID: <20240217164249.921878-11-jic23@kernel.org> (raw)
In-Reply-To: <20240217164249.921878-1-jic23@kernel.org>

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Switching to the _scoped() version removes the need for manual
calling of fwnode_handle_put() in the paths where the code
exits the loop early. In this case that's all in error paths.
