From 72c80a932074562ab4c5a6e20050997bc2f4c07d Mon Sep 17 00:00:00 2001 From: Javier Carrasco Date: Thu, 1 Aug 2024 08:13:51 +0200 Subject: [PATCH] iio: adc: ad7768-1: use device_* to iterate over device child nodes Drop the manual access to the fwnode of the device to iterate over its child nodes. `device_for_each_child_node` macro provides direct access to the child nodes, and given that they are only required within the loop, the scoped variant of the macro can be used. Use the `device_for_each_child_node_scoped` macro to iterate over the direct child nodes of the device.
