From 573dbd95964b01a942aa0c68e92b06f2c9536964 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Thu, 1 Sep 2005 17:44:29 -0700 Subject: [CRYPTO]: crypto_free_tfm() callers no longer need to check for NULL Since the patch to add a NULL short-circuit to crypto_free_tfm() went in, there's no longer any need for callers of that function to check for NULL. This patch removes the redundant NULL checks and also a few similar checks for NULL before calls to kfree() that I ran into while doing the crypto_free_tfm bits. I've succesfuly compile tested this patch, and a kernel with the patch applied boots and runs just fine. When I posted the patch to LKML (and other lists/people on Cc) it drew the following comments : J. Bruce Fields commented "I've no problem with the auth_gss or nfsv4 bits.--b." Sridhar Samudrala said "sctp change looks fine." Herbert Xu signed off on the patch. So, I guess this is ready to be dropped into -mm and eventually mainline.
