Joe Hattori 313474b108 net: mv643xx_eth: fix an OF node reference leak
[ Upstream commit ad5c318086 ]

Current implementation of mv643xx_eth_shared_of_add_port() calls
of_parse_phandle(), but does not release the refcount on error. Call
of_node_put() in the error path and in mv643xx_eth_shared_of_remove().

This bug was found by an experimental verification tool that I am
developing.

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.
