[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.
