Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ This driver should provide support for most Aztech AZT2320 based cards.
+ Several AZT2316 chips are also supported/tested, but autoprobe doesn't
+ work: all module option have to be set.
+
+ No docs available for us at Aztech headquarters !!! Unbelievable ...
+ No other help obtained.
+
+ Thanks to Rainer Wiesner <rainer.wiesner@01019freenet.de> for the WSS
+ activation method (full-duplex audio!).
