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.

--- v4: - Use the the culprit of the bug itself as the fixes tag v3: - No changes. v2: - In the Subject, fixed --> Fix - dsp --> DSP - Add Fixes tag - Changed the copyright year to 2024 in the related files v1: - Download calibrated data after loading the new DSP config params - call tasdevice_prmg_load instead of tasdevice_prmg_calibdata_load, it is unnecessary to load calibrated data after loading DSP program. Load it after loading DSP config params each time. --- sound/soc/codecs/tas2781-i2c.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
