Qualcomm Bluetooth controllers like WCN6855 do not have persistent storage for the Bluetooth address and must therefore start as unconfigured to allow the user to set a valid address unless one has been provided by the boot firmware in the devicetree. A recent change snuck into v6.8-rc7 and incorrectly started marking the default (non-unique) address as valid. This specifically also breaks the Bluetooth setup for some user of the Lenovo ThinkPad X13s. Note that this is the second time Qualcomm breaks the driver this way and that this was fixed last year by commit 6945795bc81a ("Bluetooth: fix use-bdaddr-property quirk"), which also has some further details.
