Subject: [PATCH 2/3] selftests/resctrl: Always initialize ecx to avoid build warnings
Date: Tue, 13 Aug 2024 13:45:14 +0300 [thread overview]
Message-ID: <20240813104515.19152-3-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20240813104515.19152-1-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.
