Each iteration of for_each_available_child_of_node() puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put() before the return. Additionally, the local variable ports in the function qca8k_setup_mdio_bus() takes the return value of of_get_child_by_name(), which gets a node but does not put it. If the function returns without putting ports, it may cause a memory leak. Hence put ports before the mid-loop return statement, and also outside the loop after its last usage in this function.

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.
