From 4efd587bf9f9a97608b1fcecc78a4a046c37e9b1 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Fri, 29 Sep 2006 01:58:37 -0700 Subject: [PATCH] [PATCH] Fix uninitialised spinlock in via-pmu-backlight code. The uninitialised pmu_backlight_lock causes the current Fedora test kernel (which has spinlock debugging enabled) to panic on suspend. This is suboptimal, so I fixed it.
