Bard, Oder: Is this codec even from RT564x family? To me it looks RT567x
based on RT5670_DEVICE_ID 0x6271 in sound/soc/codecs/rt5670.c.
At least sound/soc/codecs/rt5640.c: rt5640_i2c_probe() appears to find
above same value 0x6271 from the register RT5640_VENDOR_ID2.
If that's the case then one might want to ask Lenovo why they are using
completely wrong ACPI ID for the codec.
