Subject: [patch] crypto: remove a duplicate checks in __cbc_decrypt()
Date: Thu, 13 Feb 2014 17:58:32 +0300 [thread overview]
Message-ID: <20140213145832.GA11059@elgon.mountain> (raw)
We checked "nbytes < bsize" before so it can't happen here.

This doesn't change how the code works, but maybe their is a bug in the
original code. Please review?
