kismet: WARNING: unmet direct dependencies detected for

WARNING: unmet direct dependencies detected for SND_SOC_MAX98357A      Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && GPIOLIB [=n]      Selected by [y]:      - SND_SOC_INTEL_SOF_CS42L42_MACH [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_INTEL_MACH [=y] && (SND_SOC_SOF_HDA_LINK [=y] || SND_SOC_SOF_BAYTRAIL [=n]) && I2C [=y] && ACPI [=y] && SND_HDA_CODEC_HDMI [=y] && SND_SOC_SOF_HDA_AUDIO_CODEC [=y] && (MFD_INTEL_LPSS [=y] || COMPILE_TEST [=n])

I can reproduce this, but I question the hard dependency on GPIOLIB in the amplifier Kconfig:

max98357a->sdmode = devm_gpiod_get_optional(&pdev->dev, "sdmode", GPIOD_OUT_LOW);

If the gpio is optional, max98357a.c should build and compile without GPIOLIB, no?

I can't reproduce this one with Mark's for-next branch, this was fixed I believe.
