PATCH 1/1 Add support for PowerMac3,5 in snd-aoa ALSA sound module

Hello!

About two years ago Johannes Berg wrote support for the PowerMac3,6 aka G4 MDD which I was using as a desktop computer then. Johannes wrote all the code, and I tested it.

I now have a PowerMac3,5 – yes, an earlier model.

This patch makes the snd-aoa ALSA sound module support the TAS3001C codec of my Apple Power Mac G4 "Quicksilver" (2001 model). I suppose it will also work for the "Quicksilver 2002", since both identify as PowerMac3,5.

The patch also changes a few comments to name the exact Power Mac model more accurately in sound/aoa/fabrics/layout.c.

This is my first contribution to the linux kernel ever, so I hope you will be kind to me. I am not a programmer, but adding already supported devices was a task even I could accomplish.

Thanks,
Andreas aka Linux User #330250
