'Fixes: 0a0877812628 ("ASoc: tas2781: Fix spelling mistake "calibraiton" -> "calibration"")' Signed-off-by: Shenghao Ding <shenghao-ding@ti.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@intel.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. --- include/sound/tas2781-dsp.h | 7 +-- sound/soc/codecs/tas2781-fmwlib.c | 99 +++++++------------------------ sound/soc/codecs/tas2781-i2c.c | 4 +- 3 files changed, 27 insertions(+), 83 deletions(-)
