ASoC: TWL4030: Fix for digital loopback gain range
When the gain is configured using dB value it was not possible to use -24dB since the loopback got muted instead of -24dB. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@nokia.com> Acked-by: Mark Brown <broonie@opensource.wolfsomicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
