I discovered a little bug into the file drivers/sound/ac97_codec.c

It only affects the display of the PnP hexadecimal string of the codec, during 
the boot.

The function codec_id(...) has simply a nonsense code. I think someone 
forgotten to complete it.
Anyhow, here is my patch.
If it is ok for the developers, good, otherwise I will use it onluy on my 
system.
