Subject: [edk2-staging][PATCH 1/3] edk2-staging/RedfishPkg: Add interface to get question default value
Date: Wed, 7 Dec 2022 22:09:10 +0800 [thread overview]
Message-ID: <20221207140910.124-1-nicklew@nvidia.com> (raw)
Implement GetQuestionDefault() in HiiUtilityLib. Caller can get question
default value from this interface. GetQuestionDefault() is created and
modifed from SetupBrowserDxe\Setup.c under MdeModulePkg.
