4.2.8-ckt11 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Yura Pakhuchiy <pakhuchiy@gmail.com>

commit 3231e2053eaeee70bdfb216a78a30f11e88e2243 upstream.

Subwoofer does not work out of the box on ASUS N751/N551 laptops. This
patch fixes it. Patch tested on N751 laptop. N551 part is not tested,
but according to [1] and [2] this laptop requires similar changes, so I
included them in the patch.
