From 03ba6dc035c60991033529e630bd1552b2bca4d7 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Fri, 2 Feb 2024 17:37:46 +0100 Subject: [PATCH] net: dst: Make dst_destroy() static and return void. Since commit 52df157f17e56 ("xfrm: take refcnt of dst when creating struct xfrm_dst bundle") dst_destroy() returns only NULL and no caller cares about the return value. There are no in in-tree users of dst_destroy() outside of the file. Make dst_destroy() static and return void.
