   4 Subject: ASoC: fsl_asrc: Fix the issue about unsupported rate

   8 commit b06c58c2a1eed571ea2a6640fdb85b7b00196b1e upstream.
   9
  10 When the output sample rate is [8kHz, 30kHz], the limitation
  11 of the supported ratio range is [1/24, 8]. In the driver
  12 we use (8kHz, 30kHz) instead of [8kHz, 30kHz].
  13 So this patch is to fix this issue and the potential rounding
  14 issue with divider.

  17 output sample rate")
