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

So I should do this:

	SNDRV_PCM_RATES_5512 | SNDRV_PCM_RATE_8000_192000 | SNDRV_PCM_RATE_CONTINUOUS

That's not really elegant.

In the codec driver, I do that.  With ASOC, each driver specifies its own capabilities, 
and ASOC is supposed to reconcile them.  My I2S driver is not aware of the codec's 
capabilities.
