It doesn't matter whether it's like that or not.

The point is if you do it in the kernel then either you'll have very
coarse controls over the rate of data coming out of the hardware RNG,
e.g., only on/off, or you'll have to put more code in to set the rate
appropriately.

Either way it's a loss compared to doing it in user-space.
