Krzysztof Kozlowski a322b3377f pinctrl: samsung: Fix device node refcount leaks in init code
Several functions use for_each_child_of_node() loop with a break to find
a matching child node.  Although each iteration of
for_each_child_of_node puts the previous node, but early exit from loop
misses it.  This leads to leak of device node.

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.
