SubjectRe: mmotm 2020-03-11-21-11 uploaded (sound/soc/codecs/wcd9335.c)
Adding+ Masahiro Yamada for more inputs w.r.t kconfig.

Kconfig side we have:

tristate "Build all ASoC CODEC drivers"
imply SND_SOC_WCD9335

config SND_SOC_WCD9335
tristate "WCD9335 Codec"
depends on SLIMBUS

The implied symbol SND_SOC_WCD9335 should be set based on direct
dependency, However in this case, direct dependency SLIMBUS=m where as
SND_SOC_WCD9335=y. I would have expected to be SND_SOC_WCD9335=m in this

Is this a valid possible case or a bug in Kconfig?
