[alsa-devel] Cirrus Logic CS4207

[Peter-Jan Deweirdt]

Hi,

I manged myself to change the patch for the kernel 2.6.29 but it seems  
that it's not working as it should.
And I don't want to change the patch everytime I need to update the  
kernel ;)

I'll check with the person that wrote the patch how we can submit it.

Regards Peter-Jan
