>>> kismet: WARNING: unmet direct dependencies detected for CRYPTO_DEV_FSL_CAAM_BLOB_GEN when selected by TRUSTED_KEYS_CAAM

The referenced config file doesn't have anything CAAM related enabled.

I looked again at the Kconfig and CRYPTO_DEV_FSL_CAAM_BLOB_GEN depends on
CRYPTO_DEV_FSL_CAAM_JR. TRUSTED_KEYS_CAAM depends on
CRYPTO_DEV_FSL_CAAM_JR >= TRUSTED_KEYS and only then selects
CRYPTO_DEV_FSL_CAAM_BLOB_GEN, which still looks correct to me.

Could one of the authors elaborate what issue is being reported here?

Cheers,
Ahmad
