Subject: [PATCH v4 2/4] selftests/resctrl: Always initialize ecx to avoid build warnings
Date: Tue, 3 Sep 2024 17:45:26 +0300 [thread overview]
Message-ID: <20240903144528.46811-3-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20240903144528.46811-1-ilpo.jarvinen@linux.intel.com>
To avoid warnings when __cpuid_count() is an empty stub, always
initialize ecx because it is used in the return statement.
