drm/i915: initialize gt_lock early with other spin locks
commit 14c5cec5d0cd73e7e9d4fbea2bbfeea8f3ade871 upstream. commit 181d1b9e31c668259d3798c521672afb8edd355c Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sun Jul 21 13:16:24 2013 +0200 drm/i915: fix up gt init sequence fallout moved dev_priv->gt_lock initialization after use. Do the initialization much earlier with other spin lock initializations.
