commit 8964eb23408243ae0016d1f8473c76f64ff25d20 upstream.
In fimc_md_is_isp_available(), of_get_child_by_name() is called to check
if FIMC-IS is available. Current code does not decrement the refcount of
the returned device node, which causes an OF node reference leak. Fix it
by calling of_node_put() at the end of the variable 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 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.
