no member names private using make

[catweasel]

Hi Folks,

I am trying to make the drivers for a wii remote and when I run make I 
get the error below, I have had this issue for other drivers and I do 
not know what the member private requires
can anyone help please



make -C /lib/modules/2.6.28-14-generic/build M=`pwd` modules
