Subject: [PATCH v2 2/2] x86/cacheinfo: Clean out init_cache_level()
Date:   Sun, 23 Apr 2023 17:19:56 -0700
Message-Id: <20230424001956.21434-3-ricardo.neri-calderon@linux.intel.com>
In-Reply-To: <20230424001956.21434-1-ricardo.neri-calderon@linux.intel.com>
References: <20230424001956.21434-1-ricardo.neri-calderon@linux.intel.com>
Precedence: bulk

init_cache_level() no longer has a purpose on x86. It no longer needs to
set num_leaves, and it never had to set num_levels, which was unnecessary
on x86.

Replace it with "return 0" simply to override the weak function, which
would return an error.
