Yeah, I think we should move to dev_*() somehow.  At least, for
most of generic outputs with snd_printk() can be converted with more
standard functions.  It's fine that a new driver starts using
dev_*(), then we'll convert the old ones eventually later.

Debug prints with snd_printd() or snd_printdd() are different
questions, though.  We have another control factor over the behavior
of these functions, so conversions should be done carefully.
