From 8b023accc8df70e72f7704d29fead7ca914d6837 Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Mon, 14 Mar 2022 15:19:03 -0700 Subject: lockdep: Fix -Wunused-parameter for _THIS_IP_ While looking into a bug related to the compiler's handling of addresses of labels, I noticed some uses of _THIS_IP_ seemed unused in lockdep.
