Subject: [106/127] Input: i8042 - add Sony VAIO VPCZ122GX to nomux list

2.6.32-stable review patch.  If anyone has any objections, please let us know.

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

From: Dmitry Torokhov <dmitry.torokhov@...il.com>

[Note that the mainline will not have this particular fix but rather
will blacklist entire VAIO line based off DMI board name. For stable
I am being a bit more cautious and blacklist one particular product.]

Trying to query/activate active multiplexing mode on this VAIO makes
both keyboard and touchpad inoperable. Futher kernels will blacklist
entire VAIO line, however here we blacklist just one particular model.
