clang correctly complains
arch/x86/kernel/cpu/resctrl/rdtgroup.c:1456:6: warning: variable \
'h' set but not used [-Wunused-but-set-variable]
u32 h;
^
but it can't know whether this use is innocuous or really a problem.
There's a reason why those warning switches are behind a W=1 and not
enabled by default - yes, one needs to do:
make W=1 CC=clang HOSTCC=clang arch/x86/kernel/cpu/resctrl/
with clang 14 in order to trigger it.
I would normally not take a silly fix like that but this one is simple
and doesn't make the code uglier so...

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.
