Good question....

Currently not a problem because yss225.c is used only by wavfront.c which
is a driver for Turtle Beach WaveFront Series (ISA)...

Rasmus Andersen have already posted three patches
which fix my temporary braindamage (linux/init.h)...

Right know I don't care too much about hotplugging because most
of drivers are broken anyway (or not?)... I _will_ try to fix
hotplugging later (I'm talking not only about sound)... as it needs
some further investigation...
