I applied it to ALSA tree now because it's the simplest way to fix
this warning. But, I'm still wondering whether it was really wrong.

The function snd_portmap_unregister_all() is called both from the
module init and exit functions. Would the module_exit function be
called even CONFIG_MODULE=n ? If not, __init_or_module should be
correct since the function is called only from module_init.


thanks,

Takashi
