crypto: pcrypt - Rename pcrypt_instance
Steffen Klassert [Tue, 27 Jul 2010 05:16:33 +0000 (07:16 +0200)]
In the crypto-layer an instance refers usually to a crypto instance.
The struct pcrypt_instance is not related to a crypto instance.
It rather contains the padata informations, so we rename it to
padata_pcrypt. The functions that handle this struct are renamed
accordingly.
