Thanks, I was missing those bits. Actually those are in (on v4.3, starting
from drivers/char/hw_random/core.c#L483):


but as far as I can tell it only gets called once when registering the hwrng
driver, and only if the RNG driver doesn't define an init function (tpm-rng
doesn't). But that's still better than no randomness at all.
