Dropping stable

This patch is a follow-up to the one below. The USB ID is different for
the Lenovo Yoga 2 13. What Guilhem sent you was verified against Yoga 2
11 and Yoga 3 14. I guess this product line comes with a couple of
variants.

Without the quirk, no data is received from the accelerometer. I have
verified the patch, testing this on 4.3-rc4 (and 4.2 stable). With this
patch, proper orientation data is received.
