The previous commits do exactly what this entry in the TODO file asks
for, thus we can remove it now as it is no longer applicable.

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_modeset_lock_all() is still

used.



As a reference, take a look at the conversions already completed in drm core.
