I've seen that before.. (even reported it before). It just "slipped" 
into the cut'n'paste It was the following stuff that I intended to report.

Being a "stupid" user, I pick the easy way to build a fresh kernel:
1) pick the distro .config
2) make oldconfig
3) Let the kernel load what it think it needs.
4) Report if I see and strange stuff (warnings / bugs / oops) or 
misbehaviour.

So I dont know if I need that driver for anything vital. Should I care? 
Or shouldn't it "just work"?
