That's the point. It's supposed to indicate all sample rates no matter what they are or
will be. However, that may be a moot point ...

Ah! I wish this stuff were documented in the source files.
So can I do this?
static const struct snd_pcm_hardware mpc86xx_pcm_hardware = {
.rates = SNDRV_PCM_RATE_CONTINUOUS,
.rate_min = 1,
.rate_max = (unsigned int) -1,
