This breaks the build for omap2plus defconfig on arm:

/build/stage/linux/sound/soc/codecs/tpa6130a2.c:322:11: error: initialization of ‘int (*)(struct i2c_client *, const struct i2c_device_id *)’ from incompatible pointer type ‘int (*)(struct i2c_client *)’ [-Werror=incompatible-pointer-types]
  322 |  .probe = tpa6130a2_probe,
      |           ^~~~~~~~~~~~~~~
/build/stage/linux/sound/soc/codecs/tpa6130a2.c:322:11: note: (near initialization for ‘tpa6130a2_i2c_driver.probe’)
cc1: some warnings being treated as errors

You forgot to move probe() to probe_new() in the driver struct.
