[alsa-devel] OOPS: Vmaster not freed on reconfig

I'm playing around with the reconfig functions of snd-hda-codec and got 
an OOPS in slave_put. I tried to research this, and I think I've nailed 
down the problem: the vmaster is not freed on reconfig (presumably, it 
should be fixed in hda_codec.c:snd_hda_ctls_clear).
I'm a little unsure of whether the best thing is to just add it to 
codec.mixers, keep them in a separate array, or something else. What do 
you think?

(It's on 3.0, it's a sigmatel/IDT, and I've got the screen captured by a 
camera if anyone is interested.)
