Sometimes however you get a module which don't give this information. Is this intentional, signify something, or just an oversight for that config option? For example SND_HDA_CORE:
Symbol: SND_HDA_CORE [=m] Type : tristate Defined at sound/hda/Kconfig:1 Depends on: SOUND [=y] && !UML && SND [=y] Selects: REGMAP [=y] Selected by: - SND_HDA_EXT_CORE [=m] && SOUND [=y] && !UML && SND [=y] - SND_HDA [=m] && SOUND [=y] && !UML && SND [=y]
Some internal symbols don't have any visible menu-selects, because they are intended to be turned on only via other things doing 'SELECT'. After all, SND_HDA_CORE has little to no reason to be enabled unless your kernel build config asks for SND_HDA or SND_HDA_EXT_CORE (and *that* symbol is 'm', which is why SND_HDA_CORE is also ''m'. Switching EXT_CORE to 'y' will then auto-switch this one to 'y' as well).
