Subject: Re: [PATCH v3] ASoC: Intel: kbl_rt5663_rt5514_max98927: Split
 be_hw_params_fixup function

Hi Pierre

If you will take a look at the original kabylake_ssp_fixup() you will
see that it is checking whether the related FE is "Kbl Audio Port",
"Kbl Audio Headset Playback", "Kbl Audio Capture Port" or "Kbl Audio
DMIC cap" - then for the first 3 cases it sets min/max channels to 2
while for the "Kbl DMIC cap" it can be 2 or 4, that's is why I'm
trying to split this, but maybe I'm missing here something.

Best regards,
Lukasz
