cs46xx patch for XFire 4channel output not in cvs?

Hi,

as I looked into the current cvs, I noticed that the patch enabling 
4channel output for the Terratec DMX XFire didn't make it into the 
source tree.
I attached once again Benny's patch from 5th or 6th of april, with one 
minor change:
I changed the value 0x5d2d to 0x592d as Benny asked me to when I tested 
the patch.

The attached patch applies without problems to cvs snapshot from 6th of may.

thanks,
  fe
