Qian Cai ab3a9f2ccc acpi/hmat: fix an uninitialized memory_target
The commit 665ac7e927 ("acpi/hmat: Register processor domain to its
memory") introduced an uninitialized "struct memory_target" that could
cause an incorrect branching.

drivers/acpi/hmat/hmat.c:385:6: warning: variable 'target' is used
uninitialized whenever 'if' condition is false
[-Wsometimes-uninitialized]
        if (p->flags & ACPI_HMAT_MEMORY_PD_VALID) {
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/acpi/hmat/hmat.c:392:6: note: uninitialized use occurs here
        if (target && p->flags & ACPI_HMAT_PROCESSOR_PD_VALID) {
            ^~~~~~
drivers/acpi/hmat/hmat.c:385:2: note: remove the 'if' if its condition
is always true
        if (p->flags & ACPI_HMAT_MEMORY_PD_VALID) {
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/acpi/hmat/hmat.c:369:30: note: initialize the variable 'target'
to silence this warning
        struct memory_target *target;
                                    ^
                                     = NULL

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.
