Description

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

misc: ocxl: fix possible name leak in ocxl_file_register_afu()

If device_register() returns error in ocxl_file_register_afu(), 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(), and info is freed in info_release().
