This has led to one vendor reversing the address provided by the boot firmware using the 'local-bd-address' devicetree property. The only device affected by this should be the WCN3991 used in some Chromebooks. The corresponding compatible string has now been deprecated so that the underlying driver bug can be fixed without breaking backwards compatibility. Set the HCI_QUIRK_BDADDR_PROPERTY_BROKEN quirk for the deprecated compatible string and add the new 'qcom,wcn3991-bt-bdaddr-le' string to the match table for boot firmware that conforms with the binding.
