Joe Hattori d0c5fd206e regulator: of: Implement the unwind path of of_regulator_match()
[ Upstream commit dddca3b2fc676113c58b04aaefe84bfb958ac83e ]

of_regulator_match() does not release the OF node reference in the error
path, resulting in an OF node leak. Therefore, call of_node_put() on the
obtained nodes before returning the EINVAL error.

Since it is possible that some drivers call this function and do not
exit on failure, such as s2mps11_pmic_driver, clear the init_data and
of_node in the error path.

This was reported by an experimental verification tool that I am
developing. As I do not have access to actual devices nor the QEMU board
configuration to test drivers that call this function, no runtime test
was able to be performed.

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.
