2aa3176725 drm/msm: Re-order uninit function to work during probe defer 
If bind fails, we can call msm_drm_uninit before kms elements have been
created. In this case, drm_atomic_helper_shutdown will fail since there
are no drm objects. Only call drm unregistration and shutdown if drm is
registered.

Also while we're in here move the workqueue destruction to below
component_unbind since components could be actively using the wq during
uninit or in their unbind routine.

b32fa81115 drm/i915/gtt: Defer address space cleanup to an RCU worker 
Enable RCU protection of i915_address_space and its ppgtt superclasses,
and defer its cleanup into a worker executed after an RCU grace period.

In the future we will be able to use the RCU protection to reduce the
locking around VM lookups, but the immediate benefit is being able to
defer the release into a kworker (process context). This is required as
we may need to sleep to reap the WC pages stashed away inside the ppgtt.

faccd71cec drm/msm/dsi: Simplify the logic in msm_dsi_manager_panel_init() 
This patch moves things around a bit to be a little more readable and
pulls out the set_encoder_mode() call into its own function for later
use.
