I think the most intrusive change was the SMP locking. So you should compare
with other drivers while working on your own one.

Some changes are already in -current. I've asked him to split his most recent
patchset into "fixes" and "new features". I will try to commit the fixes this
week. I also want to commit the new features (slave channels), but I want t
get time to review and at least partially understand what he does before I
commit it.

Some of the changes which are in -current need to be changed (e.g. allow an
ordinary user to switch to digital out instead of having it as a root-only
switch) before we can think about merging them back to -stable.

Bye,
Alexander.
