[PATCH v1] ALSA: ASoc/tas2781: fixed wrong loading calibrated data sequence
From: Shenghao Ding
Date: Sat Apr 27 2024 - 01:30:29 EST
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.
Signed-off-by: Shenghao Ding <shenghao-ding@xxxxxx>

Change in 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.
- Remove tasdevice_prmg_calibdata_load, because it is unnecessary to load
calibrated data after loading dsp program.
- work in bypass-dsp mode even if no dsp fw loaded.
