[PATCH] ASoC: cros_ec_codec: fix kconfig dependency warning for SND_SOC_CROS_EC_CODEC

From: Necip Fazil Yildiran
Date: Thu Sep 17 2020 - 10:23:02 EST

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

Honor the kconfig menu hierarchy to remove kconfig dependency warnings.

Fixes: 93fa0af4790a ("ASoC: cros_ec_codec: switch to library API for SHA-256")
