[alsa-devel] How do I tell ALSA that my driver supports every possible sample rate?

Yes.

How could this be made more elegant?

It would be possible for ALSA to automatically set the single rate bits
that fall into the minimum/maximum range when the CONTINUOUS bit is set,
but this wouldn't help in your case because you'd still need to set
these bits in case one of the I2S/codec drivers has to remove the
CONTINUOUS bit.
