Hi Stephan,
Thanks for testing and reporting this!

Since 5.3-rc1, the kernel (correctly) complains about missing

This happens because RX1/2 MIX2 INP1 is not actually supported by
msm8916-wcd-digital for some reason. There were some traces of it
RX1/2 MIX2 path is supported by the codec with IIR1 and IIR2 inputs on INP1.
MIX2 path was not added when we added first codec support as there was
no IIR support. I think I totally missed adding this while adding IIR
support.
Better fix here would be to add that missing path.
Can you try this patch?

Subject: [PATCH] ASoC: msm8916-wcd-digital: add missing MIX2 path for RX1/2
This patch adds missing MIX2 path on RX1/2 which take IIR1 and
IIR2 as inputs.
Without this patch sound card fails to intialize with below warning:
ASoC: no sink widget found for RX1 MIX2 INP1
ASoC: Failed to add route IIR1 -> IIR1 -> RX1 MIX2 INP1
ASoC: no sink widget found for RX2 MIX2 INP1

in the initial patch, but the last remnants were removed in
commit fecd5c09ddf8 ("ASoC: msm8916-wcd-digital: remove few unused variables").
On 5.3 everything seemingly worked even with that error, but on 5.4-rc1
the sound card is no longer successfully registered:
qcom-apq8016-sbc 7702000.sound: ASoC: failed to instantiate card -19
This happens because a check for the return code of
snd_soc_dapm_add_routes() was added in
commit daa480bde6b3 ("ASoC: soc-core: tidyup for snd_soc_dapm_add_routes()").
Avoid the error by removing the routes that reference the missing widgets.
