Sorry, Clemens,

I must have messed around with too many Alsa versions on my machine, again.
Your suggested fix _does_ fix the issue!

Would you mind adding this to the git tree? Or shall I prepare a patch?

In the meantime I started a bisect session on the mainline kernel. The 
cause of this issue lies in the refactoring done last year. I couldn't 
identify the exact patch introducing the regression, though, since 
starting at step 10 the kernels would not boot. See the corresponding 
git bisect log (the last revision is the first one that would not boot).

Regards,

Felix
