[PATCH v2 0/3] Fixes and 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. This ensure the firmware is alsways running with valid coefficients.

Hi Takashi
Could you queue this patch as a bugfix for 6.2 please? The cs_dsp patch to return 1 for changed has gone into 6.2 but we missed that this hda_cs_dsp code would break.

Could you just request the cherry-pick of the necessary fix commits via stable@vger.kernel.org (with Cc to Greg / Sasha)?
I've been still traveling in this week, so it's better for you doing that by yourself.
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.
