However, not initializing all members may cause subtle issues, which are only exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is enabled. Make sure all members are fully initialized, to avoid such bugs, and to prevent future breakage when converting drivers to a different method for specifying the parents.
