From fbd41a7e5843be27386c48b3d0816e93e7865d5d Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Tue, 20 Jul 2010 11:58:00 -0700 Subject: [PATCH] drm/i915: fix deadlock in fb teardown At module unload time we'll tear down the fbdev state. We do so under the struct mutex, so we shouldn't try to use the unlocked variant of the GEM object unreference function or we may deadlock.
