From 48ee41bf5ba052364f78781e9082a510fbcd104a Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Mon, 10 Oct 2016 10:15:14 -0700 Subject: crypto: cmac - return -EINVAL if block size is unsupported cmac_create() previously returned 0 if a cipher with a block size other than 8 or 16 bytes was specified. It should return -EINVAL instead. Granted, this doesn't actually change any behavior because cryptomgr currently ignores any return value other than -EAGAIN from template ->create() functions.
