Zilin Guan 1a0072bd1f platform/x86/amd: Fix memory leak in wbrf_record() 
[ Upstream commit 2bf1877b70 ]

The tmp buffer is allocated using kcalloc() but is not freed if
acpi_evaluate_dsm() fails. This causes a memory leak in the error path.

Fix this by explicitly freeing the tmp buffer in the error handling
path of acpi_evaluate_dsm().

Fixes: 58e82a6266 ("platform/x86/amd: Add support for AMD ACPI based Wifi band RFI mitigation feature")

README 

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 reStructuredText 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.
