Dinghao Liu 4e2f83952b scsi: zfcp: Fix a double put in zfcp_port_enqueue() ... commit b481f644d9 upstream. When device_register() fails, zfcp_port_release() will be called after put_device(). As a result, zfcp_ccw_adapter_put() will be called twice: one in zfcp_port_release() and one in the error path after device_register(). So the reference on the adapter object is doubly put, which may lead to a premature free. Fix this by adjusting the error tag after device_register().
