From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> SND_SOC_DMIC depends on GPIOLIB so this driver should also depend on GPIOLIB to make kconfig happy. 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_AMD_RENOIR_MACH [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_AMD_RENOIR [=y] Fixes: 1d3776669323 ("ASoC: amd: enable build for RN machine driver") Signed-off-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Cc: Vijendar Mukunda <Vijendar.Mukunda@xxxxxxx> Cc: Mark Brown <broonie@xxxxxxxxxx> --- Found in mmotm. There are no object file build errors. I suppose that gpiolib stubs take care of that.
