drm: Fix deadlock due to getconnector locking changes
In commit ccfc0865 Author: Rob Clark <robdclark@gmail.com> Date: Thu Dec 18 16:01:48 2014 -0500 drm: tweak getconnector locking We need to extend the locking to cover connector->state reading for atomic drivers, but the above commit was a bit too eager and also included the fill_modes callback. Which on i915 on old platforms using load detection needs to acquire modeset locks, resulting in a deadlock on output probing.
