[PATCH] crypto: nx - don't err if compressed output > input

Return success instead of error if compression succeeds but the output is larger than the input. It's unlikely that the caller will use the compressed data since it's larger than the original uncompressed data, but there was no error and returning an error code is incorrect. Further, for testing

[PATCH] crypto: nx - use be32_to_cpu for __be32 field in debug msg

One of the debug messages in the NX 842 PowerNV driver is missing the required be32_to_cpu() wrapper when accessing the __be32 field csb->count. Add the wrapper so the message will show the correct count. Signed-off-by: Dan Streetman --- drivers/crypto/nx/nx-842-powernv.c | 3 ++- 1 file change

[PATCH] MAINTAINERS: change 842 NX owner email address

Change my IBM email to my personal IEEE email. I'm leaving IBM, so my email there won't work anymore. This changes the owner to my personal email, so I can still get cc'ed on patches, until someone at IBM sends a patch to take it over. Signed-off-by: Dan Streetman --- MAINTAINERS | 2 +- 1 fil
