Since commit e409dfbfccf9a49 ("ASoC: dapm: Add a few supply widget
sanity checks") the following error is seen:

 rockchip-snd-max98090 sound: HiFi <-> ff890000.i2s mapping ok
 rockchip-snd-max98090 sound: Connecting non-supply widget to supply widget is not supported (Headset Mic -> MICBIAS)
 rockchip-snd-max98090 sound: ASoC: no dapm match for Headset Mic --> (null) --> MICBIAS
 rockchip-snd-max98090 sound: ASoC: Failed to add route Headset Mic -> direct -> MICBIAS
 input: ROCKCHIP-I2S Headset Jack as /devices/platform/sound/sound/card0/input3

Invert the route between the Headset Mic and the bias in order to fix it.
