Series drm/atomic: Get rid of existing states (not really) |

The drm_atomic_get_private_obj_state() function tries to find if a
private_obj had already been allocated and was part of the given
drm_atomic_state. If one is found, it returns the existing state
pointer.

At the point in time where drm_atomic_get_private_obj_state() can be
called (ie, during atomic_check), the existing state is the new state
and we can thus replace the hand-crafted logic by a call to
drm_atomic_get_new_private_obj_state().
