i915 drm oopses while fuzzing

[Tommi Rantala <tt.rantala@gmail.com>]

Hi,

I saw these i915 oopses while fuzzing with trinity. The kernel is
mainline v3.9-rc2-188-g6c23cbb, along with these two patches from Dave
Airlie applied:

[PATCH 1/2] drm: fix idr_remove warning during fuzzing
[PATCH 2/2] drm: don't oops in ioctls that require the lock if no lock
