External kernel module?  What's all the crud on the kernel build line,
that doesn't look like how you are supposed to build a kernel module.

Anyway, I'd blame the external code, nothing I can do about that...

Lots of things changed in the kernel between 3.10 and 3.12, so to expect
external kernel modules to build properly with both of the is a bit

Did 3.12.3 work?  Have a pointer to where these drivers can be found?
Why are they outside of the kernel source tree and not included in the
main kernel.org repo?
