Hello,
and thank you for the comments.
The audio codec has been accepted on the ALSA list...
I've converted the driver to the new control framework
as Hans strongly suggested.
P.S. I thought that I sent the patches on the day I created them,
but something clearly went wrong here...

Changed EDOM to ERANGE.

Space removed...

Replaced the bool variable with a usage counter.

Rewrote the error handling in the probe function.

Fixed the TX power level handling...
