for_each_available_child_of_node() can help to iterate through the device_node, and we don't need to use while loop. Besides, the purpose of the while loop is to find a device_node which fits the condition "child_req_np == ref_np", we can just read the property of "child_np" directly in for_each_available_child_of_node(). No functional change with such conversion.

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.
