Same as before, please probe for existence.
We would be probing for /dev/tpm0. Is that really what we want that this
driver only gets compiled if /dev/tpm0 is (currently) available?
If what you say is true then this code should always be enabled.

Michael Tsirkin previously requested that there be an option for the TPM passthrough driver to be selectively enabled since at least using /dev/tpm0 may not be what everybody wants. The passthrough driver at some point will also be able to use sockets to communicate with a TPM when a file descriptor is passed to Qemu, so maybe that changes then?
