Details

In the Linux kernel, the following vulnerability has been resolved:

block: fix resource leak in blk_register_queue() error path

When registering a queue fails after blk_mq_sysfs_register() is successful but the function later encounters an error, we need to clean up the blk_mq_sysfs resources.

Add the missing blk_mq_sysfs_unregister() call in the error path to properly clean up these resources and prevent a memory leak.
