[ Upstream commit 25c0b472eab8379683d4eef681185c104bed8ffd ]
wdat_wdt_probe() calls acpi_get_table() to obtain the WDAT ACPI table but
never calls acpi_put_table() on any paths. This causes a permanent ACPI
table memory leak.
Add a single cleanup path which calls acpi_put_table() to ensure
the ACPI table is always released.
Fixes: 058dfc7670 ("ACPI / watchdog: Add support for WDAT hardware watchdog")

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.
