3.16.84-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Herbert Xu herbert@gondor.apana.org.au
commit 07bfd9bdf568a38d9440c607b72342036011f727 upstream.
On module unload of pcrypt we must unregister the crypto algorithms first and then tear down the padata structure. As otherwise the crypto algorithms are still alive and can be used while the padata structure is being freed.
