Scope-based resource management became supported also for another programming interface by contributions of Jonathan Cameron on 2024-02-17. See also the commit 59ed5e2d505bf5f9b4af64d0021cd0c96aec1f7c ("device property: Add cleanup.h based fwnode_handle_put() scope based cleanup.").

* Thus use the attribute “__free(fwnode_handle)”.

* Reduce the scope for the local variable “af01_fwnode”.

* Omit explicit fwnode_handle_put() calls accordingly.
