Put a reservation_object into drm_gem_object
Remove the ->gem_prime_res_obj callback
--------------------------------------------
This would remove the need for the ->gem_prime_res_obj callback. It would also
allow us to implement generic helpers for waiting for a bo, allowing for quite a
bit of refactoring in the various wait ioctl implementations.
The ->gem_prime_res_obj callback can be removed from drivers by using the
reservation_object in the drm_gem_object. It may also be possible to use the
generic drm_gem_reservation_object_wait helper for waiting for a bo.
Contact: Daniel Vetter
@ -469,10 +469,6 @@ those drivers as simple as possible, so lots of room for refactoring:
one of the ideas for having a shared dsi/dbi helper, abstracting away the
transport details more.
- Quick aside: The unregister devm stuff is kinda getting the lifetimes of
a drm_device wrong. Doesn't matter, since everyone else gets it wrong
too :-)

* Drivers that want to support device unplugging (USB, DT overlay unload) should
* use drm_dev_unplug() instead of drm_dev_unregister(). The driver must protect
* regions that is accessing device resources to prevent use after they're
* released. This is done using drm_dev_enter() and drm_dev_exit(). There is one
* shortcoming however, drm_dev_unplug() marks the drm_device as unplugged before
* drm_atomic_helper_shutdown() is called. This means that if the disable code
* paths are protected, they will not run on regular driver module unload,
* possibily leaving the hardware enabled.

/**
* DOC: component helper usage recommendations
*
* DRM drivers that drive hardware where a logical device consists of a pile of
* independent hardware blocks are recommended to use the :ref:`component helper
* library<component>`. For consistency and better options for code reuse the
* following guidelines apply:
*
* - The entire device initialization procedure should be run from the
* &component_master_ops.master_bind callback, starting with drm_dev_init(),
* then binding all components with component_bind_all() and finishing with
* drm_dev_register().
*
* - The opaque pointer passed to all components through component_bind_all()
* should point at &struct drm_device of the device instance, not some driver
* specific private structure.
*
* - The component helper fills the niche where further standardization of
* interfaces is not practical. When there already is, or will be, a
* standardized interface like &drm_bridge or &drm_panel, providing its own
* functions to find such components at driver load time, like
* drm_of_find_panel_or_bridge(), then the component helper should not be
* used.
