Subject: [edk2-devel][PATCH] FmpDevicePkg/FmpDxe: Use new Variable Lock interface
Date: Mon, 18 Oct 2021 04:26:47 +0000 [thread overview]
Message-ID: <SN6PR11MB25905F9B5A4C7C4904CC078996BC9@SN6PR11MB2590.namprd11.prod.outlook.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 7433 bytes --]
From: yangjie <jie.yang@intel.com<mailto:jie.yang@intel.com>>
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3655
The code in FmpDevicePkg called the deprecated interface VariableLockRequestToLock. So I changed the code in FmpDevicePkg using RegisterBasicVariablePolicy, instead of the deprecated interface.
