I've add the following patch to fix this.
commit 85e0da925b2ddbf39a6cefb4e02ad51d0a0912c0
Author: Herbert Xu <herb...@gondor.apana.org.au>
Date: Fri Mar 21 21:32:54 2014 +0800
crypto: caam - Fix first parameter to caam_init_rng
Found by the kbuild test robot, the first argument to caam_init_rng
has a spurious ampersand.
