If anyone has any objections, please let me know. ------------------ From: Javier Carrasco [ Upstream commit 6eefd65ba6ae29ab801f6461e59c10f93dd496f8 ] The iterated nodes are direct children of the device node, and the `device_for_each_child_node()` macro accounts for child node availability. `fwnode_for_each_available_child_node()` is meant to access the child nodes of an fwnode, and therefore not direct child nodes of the device node. Use `device_for_each_child_node()` to indicate device's direct child nodes.
