Weigang He fbd5b014a9 mtd: parsers: ofpart: fix OF node refcount leak in parse_fixed_partitions() 
[ Upstream commit 7cce81df7d ]

of_get_child_by_name() returns a node pointer with refcount incremented,
which must be released with of_node_put() when done. However, in
parse_fixed_partitions(), when dedicated is true (i.e., a "partitions"
subnode was found), the ofpart_node obtained from of_get_child_by_name()
is never released on any code path.

Add of_node_put(ofpart_node) calls on all exit paths when dedicated is
true to fix the reference count leak.

This bug was detected by our static analysis tool.

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 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.
