ASoC: rt5677: Fix the issue that the regmap_range "rt5677_ranges" cannot be accessed
After the patch "ASoC: rt5677: Use specific r/w function for DSP mode", the regmap_range "rt5677_ranges" was not registered in rt5677_regmap_physical, and it caused that the regmap_range "rt5677_ranges" cannot be accessed by the specific r/w function. The patch fixes this issue. Signed-off-by: Oder Chiou <oder_chiou@realtek.com> Signed-off-by: Mark Brown <broonie@kernel.org>
