Subject: Re: [PATCH] x86/sev: Do not fail SNP platform init if the vTPM cannot be registered

Only an inconsistency: no vTPM returns 0, a failed registration returns
-ENODEV, both leave sev-guest registered, and nothing reads the return
value.  The failure itself should not happen in practice and I am not
arguing otherwise.

Happy to drop this if you would rather keep the -ENODEV.

Thanks,
Gokul
