[alsa-devel] Alsa snapshot directory layout changed

I have a script that picks daily snapshots from ftp://ftp.suse.com/pub/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz ...and I just noticed that the directory layout has changed, so what was "alsa-driver" is now "alsa-driver/alsa".

Is this expected, i e, should I update my script to follow this new layout, or was it a mistake?
