Each iteration of for_each_available_child_of_node puts the previous node, but in the case of a break from the middle of the loop, there is no put, thus causing a memory leak. Upon termination of the loop (whether by break or a natural exit), either ret will have a non-zero value or child will be NULL. Hence add an of_node_put() that will execute only when ret has a non-zero value, as calling of_node_put() on a possible NULL value does not cause any further issues. Issue found with Coccinelle.

README
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 Restructured Text 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.
