And two cases of EFI_INVALID_PARAMETER are added. 1. The input values of VariableName and VendorGuid are not a name and GUID of an existing variable. 2. Null-terminator is not found in the first VariableNameSize bytes of the input VariableName buffer. This patch is to update comments for GetNextVariableName to follow them.
