OK, so I have verified it, the patch is safe.

This is tested with a new test: svolume-test, which I added in order
to be able to verify the further orcification of the svolume functions
I did. Basically it is just the testing code that was already present
in the svolume_{arm,mmx,sse,orc}.c files beefed up a bit.:
https://github.com/mkbosmans/pulseaudio/commit/cf0c5c9ad47ba0434b0518ca79ca802d0e62153a

Running svolume-test with David's patch reversed exits with an error
status and both with current git master and with my patch on top of
that succeeds.
