Hi, thanks for applying them!

I'm working my way through the "non-trivial" changes first. I have a
coccinelle script that will do a mass-conversion of the common cases.
It's possible that those changes cover the other usages in sound/* or
that I haven't made my way through the others yet (it's a very long
list). I wouldn't object to other people helping with the conversions,
of course. :)
