drm: TODO: Add DRM_MODESET_LOCK_ALL* conversion to todo.rst
We should also get the drivers using the helpers. Seems like a good intermediate TODO item. Changes in v2: - Add line about replacing drm_modest_lock_all() (Daniel) Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20181129195838.222031-1-sean@poorly.run

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.
