>>> 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

We have rechecked this report and it is indeed a false alarm. Sorry for the inconvenience.

kismet is a new tool for analyzing kconfig dependency, which is enabled in our test robot
recently, so there may still be some issues in the test flow. We have found the root cause
of this false alarm and fixed it, thanks.

Best Regards,
Yujie
