I agree with Christoph that this doesn't help any in-kernel stuff, so I
don't think it can be merged.  Why not just build these modules as part
of the normal kernel build process, the Android build system should
allow that, right?

But even if it was ok, you are adding new sysfs attributes without a
Documentation/ABI/ update, which is not ok either, so always remember
that for future patches.

thanks,
