[ Upstream commit 50b18e4a2608e3897f3787eaa7dfa869b40d9923 ]
When SND_SOC_CROS_EC_CODEC is enabled and CRYPTO is disabled, it results in the following Kbuild warning:
WARNING: unmet direct dependencies detected for CRYPTO_LIB_SHA256 Depends on [n]: CRYPTO [=n] Selected by [y]: - SND_SOC_CROS_EC_CODEC [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && CROS_EC [=y]
The reason is that SND_SOC_CROS_EC_CODEC selects CRYPTO_LIB_SHA256 without depending on or selecting CRYPTO while CRYPTO_LIB_SHA256 is subordinate to CRYPTO.
Honor the kconfig menu hierarchy to remove kconfig dependency warnings.
