commit 3bd561e1572ee02a50cd1a5be339abf1a5b78d56 upstream.
struct acpi_device_properties describes one source of properties present
on either struct acpi_device or struct acpi_data_node. When properties are
parsed, both are populated but when released, only those properties that
are associated with the device node are freed.
Fix this by also releasing memory of the data node properties.

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.
