The hash buffer is really HASH_BLOCK_SIZE bytes, someone
must have thought that memmove takes n*u32 words by mistake.

crypto: ux500 - fix checks of error code returned by devm_ioremap_resource() 2016-04-12T16:08:46+00:00 Vladimir Zapolskiy vz@mleia.com 2016-03-06T01:22:04+00:00 75efb5fe5ce23f72ef8641f593b5829152c6203c commit b62917a2622ebcb03a500ef20da47be80d8c8951 upstream. The change fixes potential oops while accessing iomem on invalid address, if devm_ioremap_resource() fails due to some reason. The devm_ioremap_resource() function returns ERR_PTR() and never returns NULL, which makes useless a following check for NULL.

Select BLKCIPHER instead of BLKCIPHER2. The latter is internal and should not be used outside of the crypto API itself. 2. Do not select ALGAPI unless you use a legacy type like CRYPTO_ALG_TYPE_CIPHER. 3. Select the algorithm type that you are implementing, e.g., AEAD. 4. Do not select generic C code such as CBC/ECB unless you use them as a fallback. 5. Remove default n since that is the default default. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
