Hi Linus,
I've attached twosound-related patches:
- the first one moves all remaining sound drivers to the
module_init/module_exit stuff. It's not really critical,
but makes another subsystem clean of the old init stuff.
- the second patch removes the softoss software synthesizer.
It does only work with the OSS/Free style sounddrivers and
has some ugly hooks in the sequencer core.
Alan has accepted this change.
Christoph
