Here's an example:
There's a function called control_hook. It is defined in a prototype
prior to its use in device_hooks. Since control_hook actually
performs a number of different behaviors, depending on the
argument, each was broken out into a separate function, which was
defined before control_hook. No other functions are going to call
these functions, so there's really no point to define prototypes for
them in the header or anywhere else.
I agree that warnings are a good thing but sometimes they just
don't serve a useful purpose. We are already going to get the
warning when a function is implicitly defined due to a missing
prototype and I think that's enough.
