Subject: [PATCH v5 2/3] ASoC: tas2781: Fix wrong loading calibrated data sequence

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")

v5:
- No change.
v4:
- Use the the culprit of the bug itself as the fixes tag.
- Better variant for tasdev_load_calibrated_data in order to much easier
to read and understand and maintain, as it makes harder to squeeze the
code.
- Fix the indentation and move operator to the previous line.
v3:
- Remove redundant return in tasdev_load_calibrated_data
- Put the second function parameter into the previous line for
tasdev_load_calibrated_data
- | Reported-by: kernel test robot <[email protected]>
| Closes: https://lore.kernel.org/oe-kbuild-all/[email protected]/
v2:
- In the Subject, fixed --> Fix
- In tas2781-fmwlib.c, tasdevice-fmw.c ---> tas2781-fmwlib.c
- dsp --> DSP
- Remove unneeded parentheses for & (dereference) operator
- Add Fixes tag
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.
- Remove tasdevice_prmg_calibdata_load, because it is unnecessary to load
calibrated data after loading DSP program.

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

This is still being used in two files. How won'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
