From f8fdadef92b7a39e9a9a83bc2df68731ac6c298b Mon Sep 17 00:00:00 2001 From: Corey Minyard Date: Fri, 16 Jul 2021 15:28:46 -0500 Subject: ipsec: Remove unneeded extra variable in esp4 esp_ssg_unref() It's assigned twice, but only used to calculate the size of the structure it points to. Just remove it and take a sizeof the actual structure. Signed-off-by: Corey Minyard Cc: Steffen Klassert Cc: Herbert Xu Cc: "David S.
