4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Robert Baronescu <robert.barone...@nxp.com>
[ Upstream commit 7aacbfcb331ceff3ac43096d563a1f93ed46e35e ]
Fix the way the length of the buffers used for
encryption / decryption are computed.
For e.g. in case of encryption, input buffer does not contain
an authentication tag.
