[edk2-devel] [PATCH v2 5/5] OvmfPkg/SmmControl2Dxe: use PcdAcpiS3Enable to detect S3 support

[Lin, Gary (HPS OE-Linux)]

To avoid the potential inconsistency between PcdAcpiS3Enable and
QemuFwCfgS3Enabled(), this commit modifies SmmControl2Dxe to detect
S3 support by PcdAcpiS3Enable as modules in MdeModulePkg do.
