[LAU] M-Audio FastTrack Pro: 24Bit/48kHz Mode and Digital I/O

[Matthias Schönborn]

Hi list,

I just realised that there's a patch for the Fast Track Pro that will enable 
24Bit/48kHz mode (if I understood it correctly) and digital in/outs. Here's 
the entry in the Alsa wiki:

http://alsa.opensrc.org/index.php/M-Audio_FastTrack_Pro

Theres a link to the patch, which itself looks like this:

# HG changeset patch

This patch adds the following capabilities to usbaudio.c:
- Merges support for M-Audio FastTrack USB
- Adds proper support for M-Audio Quattro USB
- Adds hot-reload support for all Audiophile, FastTrack and Quattro.
- FastTrack "select configuration #2" quirk is present but #ifdef'd out
pending inclusion of "usb_driver_set_configuration" function in mainline
kernel. This quirk could possibly be handled in user space anyway.

Now, how do I install it? 
I really haven't got a clue what to do with the code, any help is appreciated!
Thanks,
