[ Upstream commit 28fa3291cad1c201967ef93edc6e7f8ccc9afbc0 ]
Current implementation of of_clk_get_parent_name() leaks an OF node
reference on error path. Add a of_node_put() call before returning an
error.
This bug was found by an experimental static analysis tool that I am
developing.
Fixes: 8da411cc19 ("clk: let of_clk_get_parent_name() fail for invalid clock-indices")

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.
