Commit Message

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.

Fixes: ef3bcde75d06 ("ASoc: tas2781: Add tas2781 driver")

v4:
 - Use the the culprit of the bug itself as the fixes tag
v3:
 - No changes.
v2:
 - In the Subject, fixed --> Fix
 - Add Fixes tag
 - Changed the copyright year to 2024 in the related files
 - In tas2781-dsp.h, __TASDEVICE_DSP_H__ --> __TAS2781_DSP_H__
v1:
 - Download calibrated data after loading the new DSP config params
 - Remove tasdevice_prmg_calibdata_load, because it is unnecessary to load
   calibrated data after loading DSP program.
