Subject: [PATCH] scsi: stex: fix reboot_notifier leak in probe error path
Date: Tue, 4 Nov 2025 17:48:47 +0800 [thread overview]
Message-ID: <20251104094847.270-1-vulab@iscas.ac.cn> (raw)
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.
Fixes: 61b745fa63db ("scsi: stex: Add S6 support")
