ASoC: io: Retrieve val_bytes from the regmap API
Allow us to build infrastructure which needs to know the size of a value without requiring regmap based drivers to supply this information to both ASoC and regmap by asking regmap for the value. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
