[ Upstream commit 593ee49222a0d751062fd9a5e4a963ade4ec028a ]
acpi_fwnode_graph_parse_endpoint() calls fwnode_get_parent() to obtain the
parent fwnode but returns without calling fwnode_handle_put() on it. This
potentially leads to a fwnode refcount leak and prevents the parent node
from being released properly.
Call fwnode_handle_put() on the parent fwnode before returning to prevent
the leak from occurring.
Fixes: 3b27d00e7b ("device property: Move fwnode graph ops to firmware specific locations")

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.
