Subject: [PATCH 2/2] crypto: aesni-intel: move more common code to ablk_init_common
Date: Fri, 11 May 2012 16:00:54 +0300	[thread overview]
Message-ID: <20120511130054.26495.76435.stgit@localhost6.localdomain6> (raw)
In-Reply-To: <20120511130048.26495.55851.stgit@localhost6.localdomain6>

ablk_*_init functions share more common code than what is currently in
ablk_init_common. Move all of the common code to ablk_init_common.
