From 77dc3b173d7258329e22ad8d8407bd5f8fe97fd1 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sat, 30 Mar 2024 18:52:59 +0000 Subject: iio: adc: qcom-spmi-adc5: Use device_for_each_child_node_scoped() 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. A slightly less convincing usecase than many as all the failure paths are wrapped up in a call to a per fwnode_handle utility function. The complexity in that function is sufficient that it makes sense to factor it out even if it this new auto cleanup would enable simpler returns if the code was inline at the call site. Hence I've left it alone.
