[PATCH v1] platform/x86/intel/ifs: Initialize union ifs_status to zero

From: Kuppuswamy Sathyanarayanan
Date: Tue Jul 30 2024 - 12:02:16 EST


If the IFS scan test exits prematurely due to a timeout before
completing a single run, the union ifs_status remains uninitialized,
leading to incorrect test status reporting. To prevent this, always
initialize the union ifs_status to zero.
