This could mention that the generator function will be suffixed by
"_gen_params".

I just noticed this: the interface of this macro does not include
"prev" (which is an argument of the generated function, but not
supplied to this macro; "prev" should hopefully be explained in the
other comment you're adding for the new struct field). So, the
kernel-doc comment here should only list the actual arguments of this
macro, which is only "name" and "array".
