+Subject: crypto: s5p-sss - Fix kernel Oops in AES-ECB mode
+
+From: Kamil Konieczny <k.konieczny@partner.samsung.com>
+
+commit c927b080c67e3e97193c81fc1d27f4251bf4e036 upstream.
+
+In AES-ECB mode crypt is done with key only, so any use of IV
+can cause kernel Oops. Use IV only in AES-CBC and AES-CTR.
