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

From: David Henningsson <redacted>

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.

This one was originally targeted for 3.6+ (as mentioned in my
original patch), for earlier kernels I don't anticipate it having
any effect, neither positive nor negative. Your call.

Ah, I messed up on that, sorry, I've dropped it from the 3.0-stable
queue now.
