scsi: mpi3mr: Update timestamp only for supervisor IOCs

Ranjan Kumar · gregkh · commit 5b62f941eae8 · 2025-05-29T11:02:39.000+02:00
[ Upstream commit 83a9d30 ] The driver issues the time stamp update command periodically. Even if the command fails with supervisor only IOC Status. Instead check the Non-Supervisor capability bit reported by IOC as part of IOC Facts.
