you definetly need a inti_module/cleaup_module in every kernel module
otherwise the module count will not be decremented corectly - also it
could hang because you allocate some resources that you don't free
corectly
or keep in use (typically a non-rt process having a /dev/rtfX open and
rmmod of a module that allocated it on the rt-side -> module busy).
