From f0988e776c643a4e381e190e650ecd09b0225e50 Mon Sep 17 00:00:00 2001 From: Haotian Zhang Date: Tue, 4 Nov 2025 17:48:47 +0800 Subject: [PATCH] scsi: stex: Fix reboot_notifier leak in probe error path [ 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.
