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

From: Anssi Hannula <anssi.hannula@gmail.com>

commit e8bf069c419c1dc0657e02636441fe1179a9db14 upstream.

Audiowerk2 driver snd-aw2 is bound to any saa7146 device as it does not
check subsystem ids. Many DVB devices are saa7146 based, so aw2 driver
grabs them as well.

According to http://lkml.org/lkml/2008/10/15/311 aw2 devices have the
subsystem ids set to 0, the saa7146 default.

Fix conflicts with DVB devices by checking for subsystem ids = 0
specifically.
