From 559b5d5283ac6c0890b35e8684963e35f57f79b9 Mon Sep 17 00:00:00 2001 From: Star Zeng Date: Mon, 30 Jul 2018 10:35:09 +0800 Subject: [PATCH 1/1] FmpDevicePkg FmpDxe: Initialize DeviceLibLowestSupportedVersion Some static tool reports "DeviceLibLowestSupportedVersion" is used, but is uninitialized. It is false positive reporting based because DeviceLibLowestSupportedVersion will have assigned value after FmpDeviceGetLowestSupportedVersion() returns SUCCESS. This patch updates the code to initialize DeviceLibLowestSupportedVersion to DEFAULT_LOWESTSUPPORTEDVERSION before calling FmpDeviceGetLowestSupportedVersion(). It can pass the static tool's check.
