Why? Hardware semaphores are notorious for causing hangs. Nobody is
sharing the hardware under Linux, so I think we should enable access on
init, and not disable access until driver close. IMO the mixer should
be guarded by a Linux kernel semaphore... I have a patch from Thomas
Sailer (I think) lying around somewhere that does just that to the via
audio driver. Maybe we can adapt it.
(I cc'd this little detail, in my ali/trident.c patch review, to you)
