No, there is no reason to create an API like that - TPM's are
stateful, one cannot close the server side and re-connect

This patch implements a driver for supporting multiple emulated TPMs in a
system.
The driver implements a device /dev/vtpmx that is used to created
a client device pair /dev/tpmX (e.g., /dev/tpm10) and a server side that
is accessed using a file descriptor returned by an ioctl.
The device /dev/tpm
