Ситуация чуть хуже. Отключаем CONFIG_CRYPTO_USER_API везде.
Рекомендую сделать это вручную через menuconfig, чтобы и все
сопутствующие
CONFIG_CRYPTO_USER_API
CONFIG_CRYPTO_USER_API_HASH
CONFIG_CRYPTO_USER_API_SKCIPHER
CONFIG_CRYPTO_USER_API_RNG
CONFIG_CRYPTO_USER_API_RNG_CAVP
CONFIG_CRYPTO_USER_API_AEAD
CONFIG_CRYPTO_USER_API_ENABLE_OBSOLETE
даже не попадали в конфиг.
