    Subject[PATCH 4.5 054/101] ALSA: hda - Fix subwoofer pin on ASUS N751 and N551
    Date
    4.5-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    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.
