Fixes sdsi_meter_cert_show() to correctly decode and display the meter certificate output. Adds and displays a missing version field, displays the ASCII name of the signature, and fixes the print alignment. Fixes: 7fdc03a7370f ("tools/arch/x86: intel_sdsi: Add support for reading meter certificates") Signed-off-by: David E.
