This is not a limitation. It's just the way it is. You can't take
a reference to an object, that doesn't exist as an independent object.
So in this case, if there are no static callers of your function, the
compiler will simply ignore the inline. However, if there were other static
callers (in addition to the indirect callers through pointer), the compiler
would generate (most likely) an inline version for the static callers
and additionally a non-inline version for the indirect callers.

You are taking the pointer to the function (C adds the & for you, so you only
need the function name) and put it into the bus struct.
