This patch implements a proxy 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/tpmX is the usual TPM device created by the core TPM
driver. Applications or kernel subsystems can send TPM commands to it
and the corresponding server-side file descriptor receives these
commands and delivers them to an emulated TPM.

Thanks. So I can post a v10 where I have to re-introduce the priv field
but put it into the tpm_chip struct. Obviously it needs this field. I am
not sure whether you'll let me take the Reviewed-by and Tested-by, though?
