Yeah, some are already used.  So, they need to be listed.
But, some of (directly-) unused functions were already removed from my
new list.

snd_pcm_dump_*() are removed as they aren't used directly.
snd_pcm_dump() remains (it is already used).

The below is the revised version of white list.
The functions with '#' are to drop, and '*' are newly listed (but not
recommended to use).
