3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Henningsson <david.henningsson@canonical.com>
commit 34c3d1926bdaf45d3a891dd577482abcdd9faa34 upstream.
If this array is not cleared, the jack related code later might fail to create "Internal Speaker Phantom Jack" on Dell Inspiron 3420 and Dell Vostro 2420.
