From 80a6d7db9fa06c29c89ccce0374870ac64a81d3f Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 24 Mar 2010 21:35:23 +0800 Subject: crypto: pcrypt - Handle crypto_get_attr_type errors I was concerned about the error handling for crypto_get_attr_type() in pcrypt_alloc_aead(). Steffen Klassert pointed out that we could simply avoid calling crypto_get_attr_type() if we passed the type and mask as a parameters.
