From c376d88d4f3491ae090024b941b91bbaf1acea40 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Thu, 3 May 2012 15:44:07 +1000 Subject: [PATCH] sgi-xp: use lockdep_assert_held() !spin_is_locked() is always true on a UP build, so it cannot be used for assertions. Replace with lockdep_assert_held(). I realize UP builds are not very likely for this driver, but it's still better to fix it.
