Each loaded bus driver might make more devices available for I've had since day 0 that I've worked with TPM driver (i.e. since 2013 or 2014) that module support should be removed. I've kept the module compilation only because huge turnback from the community. It does not make sense: 1. Because it makes sense as part of "TCB". 2. "TCB" is should in be vmlinux. 3. TPM is also a subsystem with other clients in the kernel. At minimum the main TPM driver should IMHO just in vmlinux e.g. because it is rare to see distro kernel with TPM enabled and IMA disabled, I don't know any. That said, I would not mind either if TPM subsystem drivers were only y/n *except* tpm_vtpm_proxy. BR, Jarkko
