[PATCH v1 0/3] Various Fixes/Improvements for CS35L41 HDA
Fixes issue in calibration, where return codes were misinterpreted. Enable High Pass filter to reduce pops and clicks. Add improvement to ensure firmware and tuning files are always loaded together.

Function hda_cs_dsp_write_ctl() returns 3 possible values: 0 - no change, 1 - value has changed and -1 - error, so value 1 is not an error.

When you submit a patch, you must add your Signed-off-by line.
Also, this looks like no new bug, so it's worth to add Fixes tag, if any? (Not only about this patch but others, too.)
Last but not least, please make the subject prefix consistent over the patch series.
thanks,
Takashi
To ensure firmware for cs35l41 is correctly running, it is necessary that a corresponding tuning file is also loaded. Without both, the firmware may not be performing correctly Ensure that if we load the firmware, we have also loaded the correct tuning file. Otherwise, fall back to default firmware and tuning. If default tuning is also missing, then disable DSP firmware.

This helps smooth out pops and clicks in the amps.
