The core fixes balance the reference counting of the firmware nodes of the boardinfo, and keep a failed reattach from releasing an address that the target may still respond to. The rest fix the quirk selection and the unbind path of the DesignWare driver. All the patches are verified by inspection and compile testing. None of the error paths that they address were reproduced on hardware.
