Subject: [PATCH v3] ALSA: 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: 0a0877812628 ("ASoc: tas2781: Fix spelling mistake "calibraiton"
-> "calibration"")'
Signed-off-by: Shenghao Ding <shenghao-ding@...com>
---
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 <lkp@...el.com>
| Closes: https://lore.kernel.org/oe-kbuild-all/202405021200.YHInjV43-lkp@intel.com/
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
- 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
- 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.
