[ Upstream commite0686dc6f2] The reference 'child' in the iteration of for_each_available_child_of_node() is only escaped out into a local variable which is only used to check its value. So we still need to the of_node_put() when breaking of the for_each_available_child_of_node() which will automatically increase and decrease the refcount.

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.
