Ming Lei e8767b89cd block: fix kobject leak in blk_unregister_queue ... [ Upstream commit 3051247e4f ] The kobject for the queue, `disk->queue_kobj`, is initialized with a reference count of 1 via `kobject_init()` in `blk_register_queue()`. While `kobject_del()` is called during the unregister path to remove the kobject from sysfs, the initial reference is never released. Add a call to `kobject_put()` in `blk_unregister_queue()` to properly decrement the reference count and fix the leak.
