Subject: [ 14/54] ALSA: hda - Cirrus: Correctly clear line_out_pins when moving to speaker

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

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

From: David Henningsson <david.henningsson@...onical.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.
