OK, the typo fixes patch was corrected.

I am not aware of non-Intel FWHs supporting the same RNG interface.

If you're worried about people thinking their box being reported to have no
FWH when it does, then just make the message say so (i.e. add 82802 or
alike).

No, I think it helps understanding why there's no RNG device in the system.

I think that FWH connected to LPC of ICHx are not only Intel products.
For example, sst... etc.
Does rng address differ in except Intel products? 
I think that this driver is targeting Intel FWH.
Therefore, printk() was removed.
