GEM objects can now have a function table instead of having the callbacks on the
DRM driver struct. This is now the preferred way and drivers can be moved over.
Use DRM_MODESET_LOCK_ALL_* helpers instead of boilerplate
---------------------------------------------------------
For cases where drivers are attempting to grab the modeset locks with a local
acquire context. Replace the boilerplate code surrounding
drm_modeset_lock_all_ctx() with DRM_MODESET_LOCK_ALL_BEGIN() and
DRM_MODESET_LOCK_ALL_END() instead.
This should also be done for all places where drm_modest_lock_all() is still
used.
As a reference, take a look at the conversions already completed in drm core.
