The VPD update path serializes the same call\nunder optrom_mutex, so this reset path can interleave its flash register\naccesses with a concurrent VPD or optrom flash operation and corrupt the\nreads.\n\nHold ha-\u003eoptrom_mutex across the get_flash_version() call to match the\nVPD update path.",
