When the output sample rate is [8kHz, 30kHz], the limitation of the supported ratio range is (1/24, 8). In the driver we use (8kHz, 30kHz) instead of [8kHz, 30kHz]. So this patch is to fix this issue and the potential rounding issue with divider.

Using one of the conditions: if (inrate > 8 * outrate) pair_err();
This means: if (inrate <= 8 * outrate) /* Everything is fine */
So the supported ratio range is still [1/24, 8] right?
Oh, yes, should still [1/24, 8].
Thanks
