Thank you for the heads-up. Actually, this section of the
documentation describes the theoretical representation of counter
devices, as opposed to the in-kernel implementation of the Generic
Counter interface. As such, the phrase "unsigned integer" here means a
natural number and not the C language "unsigned int" data type.

I'm going to update this line to state that clearer since it can be
easily confused in the context of the rest of the document.
