I believe this is on top of Philippe's "[PATCH v2 2/2] tpm: Return QMP
error when TPM is disabled in build"

Based-on: <20210609184955.1193081-3-philmd@redhat.com>

However, it should probably go *first*, so the additional 'if' to
suppress warnings about unused qmp_marshal_output_TpmFOO() can be
squashed into Philippe's patch.

Apart from that, this looks good to me!

Additional 'if':

No, my series is stand-alone.
