[PATCH v5 1/3] ASoC: tas2781: Fix wrong loading calibrated data sequence
Remove declaration of unused API which load calibrated data in wrong sequence, changed the copyright year and correct file name in license header.

Calibrated data will be set to default after loading DSP config params, which will cause speaker protection work abnormally. Reload calibrated data after loading DSP config params.

AFAICS the i2c glue driver still uses this, how can't this break the build?

[PATCH v5 3/3] has removed tasdevice_prmg_calibdata_load, and tasdevice_prmg_load(tas_priv, 0) has been called instead of tasdevice_prmg_calibdata_load
-- With Best Regards, Andy Shevchenko
Use the API with correct sequence instead of the wrong one.

This is still being used in two files. How won't this break the build?
