It changes the crypto/Kconfig file and adds the CRYPTO_RSA config option: +config CRYPTO_RSA + tristate "RSA algorithm" + select AKCIPHER [...] The symbol AKCIPHER, however, is not defined in Kconfig. Did you maybe mean CRYPTO_AKCIPHER, which you added in commit 3c339ab83fc0 ("crypto: akcipher - add PKE API")? I detected the issue by running undertaker-checkpatch from the Undertaker tool suite (https://undertaker.cs.fau.de) as part of an automated, daily analysis of the most recent linux-next tree. There is also a tool in the Linux tree itself that can detect such issues (scripts/checkkconfigsymbols.py). Regards, Andreas
