Hi,
I'm trying to enable the max98357a codec in sound/soc/codecs.
In the Kconfig file it is listed with an empty tristate so it doesn't show
up when I do a make menu config.
The only way I found so far was to patch the Kconfig and add a description
to the tristate. It then appears in the menu when doing make menuconfig
and it is also enabled if i patch my board's defconfig and add
CONFIG_SND_SOC_MAX98357A=m to it. If I don't add a description then adding
CONFIG_SND_SOC_MAX98357A=m doesn't enable it.
How can I enable it without adding a description to the tristate?
Thanks

That's usually a result of the variable being enabled by a 'select' elsewhere.

Enable something that does a 'select'. Look in a 'git grep MAX98357A'
or "find . -name 'Kconfig*' | xargs grep MAX98357A' . It looks like that
part is mostly used for some arm64 (it's in the defconfig) and some
Intel SoC boards. Look at sound/soc/intel/boards/Kconfig.

Many thanks, I see what you mean, they are enabled at the board level
(Intel, amd and rockchip). I'll patch mine (sunxi) and the defconfig.
