When SND_SOC_STM32_DFSDM is selected, and GPIOLIB is not selected, Kbuild gives the following warning: WARNING: unmet direct dependencies detected for SND_SOC_DMIC Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && GPIOLIB [=n] Selected by [y]: - SND_SOC_STM32_DFSDM [=y] && SOUND [=y] && !UML && SND [=y] && (ARCH_STM32 || COMPILE_TEST [=y]) && SND_SOC [=y] && STM32_DFSDM_ADC [=y] This is because SND_SOC_STM32_DFSDM selects SND_SOC_DMIC without selecting or depending on GPIOLIB, despite SND_SOC_DMIC depending on GPIOLIB. This unmet dependency bug was detected by Kismet, a static analysis tool for Kconfig. Please advise if this is not the appropriate solution.
