6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@xxxxxxxxxxxxxxx>
[ Upstream commit 3114f77e9453daa292ec0906f313a715c69b5943 ]
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.
Fixes: 2b40e654b73a ("platform/x86/intel/ifs: Add scan test support")
