| Subject: [PATCH] smm_gateway: GetNextVariableName Fix |
| |
| GetNextVariableName() should return EFI_BUFFER_TOO_SMALL |
| when NameSize is smaller than the actual NameSize. It |
| currently returns EFI_BUFFER_OUT_OF_RESOURCES due to setting |
| max_name_len incorrectly. This fixes max_name_len error by |
| replacing it with actual NameSize request by u-boot. |
