Add scoped versions of fwnode child node iterators that automatically handle reference counting cleanup using the __free() attribute: - fwnode_for_each_child_node_scoped() - fwnode_for_each_available_child_node_scoped() These macros follow the same pattern as existing scoped iterators in the kernel, ensuring fwnode references are automatically released when the iterator variable goes out of scope. This prevents resource leaks and eliminates the need for manual cleanup in error paths. The implementation mirrors the non-scoped variants but uses __free(fwnode_handle) for automatic resource management, providing a safer and more convenient interface for drivers iterating over firmware node children.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
