Javier Carrasco 77adf4b1f3 spmi: pmic-arb: fix return path in for_each_available_child_of_node()
This loop requires explicit calls to of_node_put() upon early exits
(break, goto, return) to decrement the child refcounter and avoid memory
leaks if the child is not required out of the loop.

A more robust solution is using the scoped variant of the macro, which
automatically calls of_node_put() when the child goes out of scope.

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.
