Downgrade to 4.1.24, because 4.1.28 turns out to be quite buggy:
- broken backport of 8f182270dfec "mm/swap.c: flush lru pvecs on compound page arrival"
- some bug resulting in soft lockup on iptables call
There are fixes queued for 4.1.29 already...
Since this driver is already included in mainline 4.6, lets integrate it
into main kernel package instead of keeping as separate DKMS package.
