[ Upstream commit 20da637eb545b04753e20c675cfe97b04c7b600b ]
In stex_probe(), register_reboot_notifier() is called at the beginning, but if any subsequent initialization step fails, the function returns without unregistering the notifier, resulting in a resource leak.
Add unregister_reboot_notifier() in the out_disable error path to ensure proper cleanup on all failure paths.
