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. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>
