Mark Salter 500a988948 drivers/perf: thunderx2_pmu: Fix memory resource error handling
[ Upstream commit 688494a407d1419a6b158c644b262c61cde39f48 ]

In tx2_uncore_pmu_init_dev(), a call to acpi_dev_get_resources() is used
to create a list _CRS resources which is searched for the device base
address. There is an error check following this:

   if (!rentry->res)
           return NULL

In no case, will rentry->res be NULL, so the test is useless. Even
if the test worked, it comes before the resource list memory is
freed. None of this really matters as long as the ACPI table has
the memory resource. Let's clean it up so that it makes sense and
will give a meaningful error should firmware leave out the memory
resource.

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 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.
