The regression is caused by a missing backport: 6.12.114 picked up "Bluetooth:
L2CAP: convert to getsockopt_iter" but not its prerequisite "net: call
getsockopt_iter if available" (upstream 5bd0dec150f5), so getsockopt() on
L2CAP sockets fails with EOPNOTSUPP and bluetoothd cannot register the adapter.

If someone can test it, a Tested-by in reply to the patch would help.
