When SND_SOC_INTEL_KBL_DA7219_MAX98357A_MACH is selected, and GPIOLIB is not selected, Kbuild gives the following warnings: 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_DA7219_MAX98357A_GENERIC [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_INTEL_MACH [=y] 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_INTEL_DA7219_MAX98357A_GENERIC [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_INTEL_MACH [=y] WARNING: unmet direct dependencies detected for SND_SOC_INTEL_DA7219_MAX98357A_GENERIC Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_INTEL_MACH [=y] && GPIOLIB [=n] Selected by [y]: - SND_SOC_INTEL_KBL_DA7219_MAX98357A_MACH [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_INTEL_MACH [=y] && SND_SOC_INTEL_KBL [=y] && I2C [=y] && ACPI [=y] && (MFD_INTEL_LPSS [=y] || COMPILE_TEST [=n]) This is because SND_SOC_DMIC and SND_SOC_MAX98357A are selected by SND_SOC_INTEL_DA7219_MAX98357A_GENERIC, which is also selected by SND_SOC_INTEL_KBL_DA7219_MAX98357A_MACH. However, the selectors do not depend on or select GPIOLIB, despite SND_SOC_DMIC and SND_SOC_MAX98357A depending on GPIOLIB. These unmet dependency bugs were detected by Kismet, a static analysis tool for Kconfig. Please advise if this is not the appropriate solution.
