Subject: [patch] crypto: drbg - fix an error code in drbg_init_sym_kernel()
Date: Fri, 17 Jun 2016 09:16:19 +0000	[thread overview]
Message-ID: <20160617091618.GC25609@mwanda> (raw)

We accidentally return PTR_ERR(NULL) which is success but we should
return -ENOMEM.

Fixes: 355912852115 ('crypto: drbg - use CTR AES instead of ECB AES')
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
