__drm_atomic_helper_plane_state_reset() is used to initialize a newly allocated drm_plane_state, and is being typically called by the drm_plane_funcs.reset implementation.
Since we want to consolidate DRM objects state allocation around the atomic_create_state callback that will only allocate and initialize a new drm_plane_state instance, we will need to call __drm_atomic_helper_plane_state_reset() from both the reset and atomic_create hooks. To avoid any confusion, we can thus rename __drm_atomic_helper_plane_state_reset() to __drm_atomic_helper_plane_state_init().
