The commit referenced moves the hwrng_register() call to the ->scan()
callback instead of it being in probe(). This was done to ensure the
virtio-rng devices can contribute to the initial system entropy
introduced in commit d9e7972619334.

That patch is quite small too, but will need a slight conflict
resolution due to the previous two code-shuffling patches, and also
the following revert.

However, I decided against the backport of the ->scan() method, since
it wasn't designed to solve this regression, it happens to solve it,
and it actually introduces new functionality. I would be happy to
provide a backport of the relevant patches, if you think that would be
alright.

Thanks,

Amit
