[ Upstream commit fc340115ffb8235c1bbd200c28855e6373d0dd1a ]
This patch fixes cts(cbc(aes)) test when cbc-aes-ppc4xx is used.
alg: skcipher: Test 1 failed (invalid result) on encryption for cts(cbc-aes-ppc4xx)
00000000: 4b 10 75 fc 2f 14 1b 6a 27 35 37 33 d1 b7 70 05

alg: skcipher: Failed to load transform for cts(cbc(aes)): -2
The CTS cipher mode expect the IV (req->iv) of skcipher_request
to contain the last ciphertext block after the {en,de}crypt
operation is complete.
Fix this issue for the AMCC Crypto4xx hardware engine.
The tcrypt test case for cts(cbc(aes)) is now correctly passed.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
