Christian A. Ehrhardt b9d760dae5 of: Fix double free in of_parse_phandle_with_args_map 
[ Upstream commit 4dde835698 ]

In of_parse_phandle_with_args_map() the inner loop that
iterates through the map entries calls of_node_put(new)
to free the reference acquired by the previous iteration
of the inner loop. This assumes that the value of "new" is
NULL on the first iteration of the inner loop.

Make sure that this is true in all iterations of the outer
loop by setting "new" to NULL after its value is assigned to "cur".

Extend the unittest to detect the double free and add an additional
test case that actually triggers this path.

Fixes: bd6f2fd5a1 ("of: Support parsing phandle argument lists through a nexus node")

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.
