Hi Takashi, Mark
It's the call in sound/last.c. Only devices that have been preoprly regstered at this point of __init calls are shown. So, it's often misleading.
I keep wondering if we should just remove it due to confusion like this.
I don't mind to get rid of it at all. But maybe it'd be good to have an alternative debug (or info) print, e.g. showing at each card registration.
If I used late_initcall_sync() for it, the boot log became below.
