we are using an I2C connected ti,tlv320aic3007. During probe, regmap_register_patch() returns -6, which leads to the error message: "tlv320aic3x 2-0018: Failed to init class D: -6". I think this is because the codec is still in reset and does not respond to the I2C

How to get rid of the error message? Power on the codec, just to write the register sequence or don't print the error message on "-6"?

Yes, power on the CODEC - if you're applying a patch the expectation is that it should actually be applied to the device, otherwise things might get confused later.
