CVE-2022-49780

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

scsi: target: tcm_loop: Fix possible name leak in tcm_loop_setup_hba_bus()

If device_register() fails in tcm_loop_setup_hba_bus(), the name allocated by dev_set_name() need be freed. As comment of device_register() says, it should use put_device() to give up the reference in the error path. So fix this by calling put_device(), then the name can be freed in kobject_cleanup(). The 'tl_hba' will be freed in tcm_loop_release_adapter(), so it don't need goto error label in this case.

A memory leak was identified in tcm_loop_setup_hba_bus() where the name allocated via dev_set_name() was not released when device_register() failed. The issue is resolved by adding put_device() in the error path, ensuring proper cleanup via kobject_cleanup().
