[PATCH] fix crasher in ALSA module on newer PowerBook and mini

[John S. S. <to...@to...>]

Hi Matthias,

Recently I came across a bug in the Ubuntu bug tracker, which described
a crash in the ALSA module. The bug is documented at
<https://launchpad.net/distros/ubuntu/+source/pbbuttonsd/+bug/39646>. It
is a crash which occurs on some of the newer machines which don't have a
hardware mixer. Essentially it's a (hard to track down) typo; the patch
is below.

cheers,

John
