Cannot see source code for this kernel object

The web page that links to this repository says "The USB Wi-Fi module we use is based on a Realtek Chip (rtl8192cu). We found the Realtek drivers included with the Ubuntu Oneiric 11.10 build a bit flakey so we compiled and open sourced our own." The file in this repository is a compiled kernel object.

Where is your kernel code? Can you express the changes to this driver as a patch?
