Subject: crypto: rsa - select on undefined AKCIPHER

Hi Tadeusz,

your commit cfc2bb32b313 ("crypto: rsa - add a new rsa generic
implementation") was merged into linux-next today (i.e., next-20150618).
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
