Subject: [PATCH] thunderbolt: Fix a leak in tb_retimer_add()
Git-commit: bec4d7c93afc07dd0454ae41c559513f858cfb83
References: git-fixes
Patch-mainline: v5.12-rc7
After the device_register() succeeds, then the correct way to clean up
is to call device_unregister(). The unregister calls both device_del()
and device_put(). Since this code was only device_del() it results in
a memory leak.
