The layering violation which Brian identified does need fixing. However
please don't take this patch as it currently is, as it causes a NULL
ptr dereference.

I can send an updated version in a moment which: -
1) Fixes the conflict you will get when applying it for v4.1
   (due to my "st_configure_oob must be called after IP is clocked" patch).

2) Fixes the crash which this patch introduces.

regards,

Peter.
