Hi
I do not suggest we use below check.
if (RETURN_ERROR (AsciiStrToGuid (Value, Guid))) {
I suggest we use below style, because it may help source level debug to see
what Status is returned.
Status = AsciiStrToGuid (Value, Guid);
if (EFI_ERROR (Status)) {
The suggestion is applied to all patches, such as CapsuleApp
Thank you
