[PATCH 4/8] conf: Move _virDomainTPMDef::version into _virDomainTPMDef::data::emulator
Michal Privoznik

Mon Jul 18 09:30:46 UTC 2022
The _virDomainTPMDef structure has 'version' member, which is a
bit misplaced. It's only emulator type of TPM that can have a
version, even our documentation says so:
``version``
The ``version`` attribute indicates the version of the TPM. This attribute
only works with the ``emulator`` backend. The following versions are
supported:
Therefore, move the member into that part of union that's
covering emulated TPM devices.
