Perhaps better would be to add and use some combination of
type specific logging message functions/macros like:

void snd_<level>(const struct snd_device *dev, const char *fmt, ...)
void snd_card_<level>(const struct snd_card *card, const char *fmt, ...)
void snd_ac97_<level>(const struct snd_ac97 *ac97, const char *fmt, ...)

allowing NULL as the type pointer when necessary/appropriate.
